Saturn OBD2 codes
Codes where we have reviewed, vehicle-specific evidence for this make.
Saturn's notes come from GM bulletins shared with Chevrolet: a cold-weather no-crank tied to the anti-theft system on the 2003 to 2006 ION, and stretched timing chains on the 3.6L V6 in the 2007 Aura. We have not confirmed these bulletins are still current.
B0092 that returns after the passenger presence module is replaced
An owner complaint on a 2007 Ion describes an airbag readiness light with B0092 in the passenger presence system. The passenger seat module was replaced without a lasting fix, and the light came back within a few miles. Airbag faults need proper testing, so have the system inspected by a qualified shop rather than repaired at home. The source is an owner complaint filed with NHTSA, so this is owner-reported vehicle data and not confirmed by a bulletin.
B2960 with a cold-weather no crank, no start
GM bulletin 04-08-45-005 covers a no crank, no start in cold weather with B2960 on the 2003 to 2006 Saturn Ion. If the car will not crank on cold mornings and these codes are stored, ask a dealer about this bulletin. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
C0045 set as wheel speed sensor codes
GM bulletin PIT4586 covers C0045 set in the brake control module on the 2008 Saturn Vue, and calls them wheel speed sensor codes. The vehicle note points to the rear sensor harness. Only the NHTSA summary was read. Brakes are safety-critical, so have the vehicle inspected by a qualified shop. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
C0050 with the ABS light on rear wheel speed sensor circuits
GM bulletins summarised by NHTSA tie C0050 to the ABS light with rear wheel speed sensor circuits, connectors, debris on the tone ring or module reprogramming. Row notes mention oil on a rear sensor and a wire pulling out of a connector on some vans. This is a brake system, so have it inspected by a qualified shop. We read only the NHTSA summaries. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
C0161 with faulty brake lights and cruise control
GM bulletin SB-08-05-22-009A covers intermittent brake lights, extra pedal travel to shift out of park and cruise control that does not work, with C0161 stored, on 2004 to 2009 mid-size cars. The ABS computer is flagging the brake pedal switch signal. The summary does not describe the repair. Brake system faults are safety-critical, so have the vehicle inspected before relying on it. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
C0186 from a chafed brake module harness
GM bulletin PIT-4756 covers ABS and StabiliTrak lights with C0186 on 2007 to 2009 Equinox, Torrent and Vue. It says the cause can be the wire harness to the brake module chafing on the transmission mount or a metal bracket. Brake system faults are safety-critical, so have the vehicle inspected before relying on it. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
C0287 with an intermittent ABS light on hybrids
GM bulletin PIC-4936 covers an ABS light that comes on intermittently with C0287 on the 2009 hybrid Malibu and Aura. The NHTSA summary gives no cause. Brake system faults are safety-critical, so have the vehicle inspected before relying on it. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
C0550 among power steering codes
GM bulletin 07-02-32-007 lists C0550 among the codes for a power steering that is inoperative or hard to turn on the Ion, Cobalt, HHR and G5. It gives diagnostic tips for a power steering message. We only read the NHTSA summary. Steering is safety critical, so have it inspected by a qualified shop. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
P000B from cracked cam actuator solenoid screens
Saturn bulletin PIP-4644 says P000B on the 2008 to 2009 Astra may be caused by one or both cam actuator solenoid filter screens having cracked. Check the cam actuator solenoid filter screens early, along with the oil level and condition. Only the NHTSA summary was read, not the full bulletin. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
P0019 from stretched timing chains on the 3.6L V6
GM bulletin 07-06-01-014 ties cam timing codes including P0019 on the 2007 LY7 3.6L V6 to stretched primary and secondary timing chains, and replaces the primary chain and both secondary chains. Check the oil level and condition first. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
P0133 from a slow response oxygen sensor
Saturn bulletin 00T02 covers the service engine soon light with P0133 (oxygen sensor 1 slow response) on some 2000 S-Series cars. We only read the NHTSA summary, which does not give the repair. Check the sensor and its wiring first. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
P0201 and P0203 among injector and misfire codes
GM bulletin PIP4924C is preliminary information about a service engine soon light and misfire, and it lists P0201 and P0203 among many injector and misfire codes. The vehicle notes apply it to the 2009 to 2015 Traverse and 2009 to 2010 Outlook. Check for a misfire and look at the injector and its wiring first. Only the NHTSA summary was read, not the bulletin itself. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
P0221 with a reduced power lamp
Saturn bulletin 030604043 covers a check engine light and possible reduced power lamp with P0221 and related throttle position codes on some Saturn models. The NHTSA summary gives no cause, so check the throttle body and its wiring first. Only the NHTSA summary was read, not the bulletin itself. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
P0453 with the check engine light on a 2004 Vue
Saturn bulletin 040604052 covers a check engine light with P0453 stored in the PCM on the 2004 Vue. Two bulletins for this vehicle name the code, but the summaries we read do not say the fix. We have not confirmed the status, so this is labelled vehicle data rather than confirmed by bulletin.
P0461 with a false low fuel gauge
Saturn bulletin 02-T-38 covers a fuel gauge that reads falsely low or stuck on empty, sometimes intermittently, with P0461 possibly set on 2002 to 2003 Vue. Only the NHTSA summary was read. Check the fuel level sender and gauge reading first. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
P0571 with cruise control not working
Saturn bulletin 04086804 covers a 2004 Vue where cruise control does not work, the service engine soon light may be on, and P0571 is stored in the powertrain control module. We only read the NHTSA summary, which does not give a repair. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
P0604 from internal ECM faults
GM bulletin 4198 says the service engine soon light on the 2007 and 2008 Saturn Sky and Pontiac Solstice may come on because of internal ECM codes, including P0604. We only read the NHTSA summary, which does not give a repair. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
P0638 with a reduced power lamp after cold starts on the Saturn L-Series
GM bulletin 04-06-04-085 covers a service engine soon or reduced power lamp with P0638 after a cold start in subfreezing temperatures on the L-Series. The summary does not say what the fix is. Look at the battery and wiring first when the problem only shows up in the cold. We only read the NHTSA summary, not the full bulletin. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
P069E with long cranking from the fuel pump control module
GM bulletin 08-06-04-042 covers a check engine light or extended crank time with P069E stored on 2008 to 2009 Vue models, and points to the fuel pump control module. Check the module and its connections first. The bulletin is published on NHTSA, but we have not confirmed it is still current, so this is labelled vehicle data rather than confirmed by bulletin.
P0752 with transmission computer problems
An owner of a 2007 Saturn Outlook reports that the dealer read P0752 with other codes and described transmission computer issues. It is a single report, so have the codes read in full. This comes from owner reports to NHTSA, not a bulletin, so it is labelled vehicle data rather than confirmed by bulletin.
P0989 and the transmission fluid pressure switch check
GM bulletin 070730015 gives information on a transmission fluid pressure switch check for false codes, including P0989, on 6T70, 6T75, 6L50, 6L80 or 6L90 automatics. The vehicle notes list some Saturn, Buick and Cadillac models, with an owner reporting a pressure sensor repair. The bulletin PDF was not read, so the procedure is unknown. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
P0989 with a van stuck in first gear
An NHTSA owner complaint on a 2008 Saturn Vue reports a failure to shift from first gear with P0989 among the codes pulled. A transmission shop rebuilt the transmission, which included a failed wave plate. No bulletin was found, and it needs testing to confirm any link. The source is owner reports, not a diagnosis.
P0AA1 that can set with a hybrid battery light
GM bulletin 070603004 covers a hybrid battery light and check engine light on the 2007 Vue, and says P0AA1 may also set. The fix in the summary is an engine wiring harness jumper for the starter and generator resolver circuit. We read only the NHTSA summary. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
P1174 from a fuel injector concern
GM bulletin PIP4017C tells dealers to test the fuel injectors for P1174 on the 2006 to 2007 Malibu and the 2007 Saturn Vue, Aura and Sky. We only read the NHTSA summary. Injector testing is the first step. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
P1811 with the service lamp and long shifts
Saturn bulletin 02-T-84 and a related GM bulletin cover the service lamp with P1811 and long shifts on L-Series cars. The summary names the code as maximum adapt.
