B2290 with an airbag light that is hard to reproduce

Supported by vehicle data

Ford bulletin 06202 covers an airbag light with B2290 on 2006 Ford and Mercury cars, and notes the fault is difficult to duplicate. We only read the NHTSA summary, so the cause is not stated here. Because this is an airbag warning, 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.

• B2290: Occupant classification system fault, front passenger seat (Mercury)

B2290 read as a passenger seat sensor fault in an owner complaint

Supported by vehicle data

An owner complaint on a 2008 Mercury Milan reads B2290 as an occupant classification status fault for the front passenger side, with a garage pointing to the sensor under the passenger seat. This is one owner statement and has not been verified. This system is tied to the airbag, so have it inspected by a qualified shop. The source is owner reports, so this is labelled vehicle data rather than a confirmed fix.

• B2290: Occupant classification system fault, front passenger seat (Mercury)

B2292 with the airbag lamp on the Explorer and Mountaineer

Supported by vehicle data

Mercury bulletin 16618 covers an airbag warning lamp with B2292 on the 2002 to 2003 Explorer and Mountaineer. The NHTSA summary names only the code and the lamp, so it gives no cause or fix. Airbag work is safety-critical, so have the system inspected rather than repaired at home. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

• B2292: Seat belt pretensioner circuit fault (Ford)

C1236 with the ABS lamp on and a differential-mounted sensor

Supported by vehicle data

Mercury bulletin 03263 covers an ABS lamp with C1236 on 2004 Mountaineer models that have a differential-mounted rear wheel speed sensor. We only read the NHTSA summary, which does not state a fix. ABS is a safety system, 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.

• C1236: Left rear wheel speed sensor input missing (Ford)

C1237 with the ABS light on

Supported by vehicle data

Ford bulletins 14900 and 03263 cover the ABS light with C1237 on the Mountaineer and 2002 Explorer. Only the NHTSA summaries were read and the repair is not stated. Brake and stability faults are safety-critical, so have the system inspected rather than attempting repairs yourself. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

• C1237: Primary brake pressure sensor signal (Hyundai) or rear wheel speed sensor (Ford)

P0155 from the PCM calibration

Supported by vehicle data

Ford bulletin 12515 attributes P0155 on the 1998 Taurus and Sable to the powertrain control module calibration. We read only the NHTSA summary, not the bulletin itself. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

• P0155: Heater circuit fault on the upstream oxygen sensor on the second bank of cylinders (bank 2, sensor 1)

P0460 in continuous memory, Crown Victoria family

Supported by vehicle data

Mercury bulletin 18222 covers the check engine light with P0460 in continuous memory on 2003 and 2004 Crown Victoria, Grand Marquis and Town Car models. We only read the NHTSA summary, so the repair is not known. Check the gas cap and EVAP system first. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

• P0460: Fuel level sensor circuit fault

P0713 with a flashing transmission indicator lamp

Supported by vehicle data

Ford bulletin 01107 covers a flashing transmission control indicator lamp on 2002 Explorer and Mountaineer models with a 5R55W built between 11/13/2000 and 3/8/2001. P0713 is the code most often retrieved and may come from water getting into the transmission solenoid body connector. Check that connector first. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

• P0713: Transmission fluid temperature sensor A circuit, high input

P0718 with harsh shifts on 6F50 transaxles

Supported by vehicle data

Ford TSB 07-3-11 covers 6F50 transaxles built before 1 January 2007 with P0718 and harsh engagement, no upshift or fifth gear only. It applies to some Ford, Lincoln and Mercury models, and a 2008 Edge owner complaint quotes it. 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.

• P0718: Turbine (input) shaft speed sensor signal drops in and out

P0723 with high rpm and no hard shifting

Possible — needs testing

An NHTSA complaint on a 2005 Sable reports P0723 with a check transmission light and high rpm without hard shifting. The owner says the transmission was rebuilt at about 68,000 miles. This needs testing to confirm, and it is an owner report only.

• P0723: Output shaft speed sensor signal drops in and out

P1233 from chafed wiring at a transmission connector

Supported by vehicle data

Ford bulletin 14041 says wiring chafed on top of the transmission pan, or on the bracket that holds connector C140, can set P1233 and related codes, with shifting concerns, on the 2000 Taurus and Sable. 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.

• P1233: On Ford vehicles, the engine computer cannot communicate with the fuel pump driver module, so the module is reported off line

P1233 with an intermittent no-start

Supported by vehicle data

Ford bulletin 17592 covers an intermittent no-start or a warning light with a range of codes including P1233 on the 2004 Explorer and Mountaineer. The NHTSA summary does not state the repair. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

• P1233: On Ford vehicles, the engine computer cannot communicate with the fuel pump driver module, so the module is reported off line

P1233 with a possible driveability or no-start condition

Supported by vehicle data

Ford bulletin 17745 covers P1233 with a possible driveability or no-start condition on 2003 to 2004 Crown Victoria, Grand Marquis and Town Car models. The NHTSA summary does not state the repair, and we only read that summary. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

• P1233: On Ford vehicles, the engine computer cannot communicate with the fuel pump driver module, so the module is reported off line

P1A0C with a Stop Safely Now message

Supported by vehicle data

Ford bulletin 08-3-3 covers an intermittent red triangle and Stop Safely Now message with the wrench light and P1A0C on the hybrid versions only of the 2005 Escape and 2008 Mariner. A later Ford bulletin describes the same message on the Mariner Hybrid. We only read the NHTSA summary, so it names no cause. Have the hybrid system inspected. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

• P1A0C: On Ford hybrids, the hybrid powertrain controller disabled the engine (Stop Safely Now message)

P2067 from an improperly installed remote start system

Supported by vehicle data

Ford bulletin 17512 attributes an intermittent warning light with P2067, both fuel level sensor circuit low codes, to an improperly installed remote start system. It covers some 2003 to 2004 Ford, Lincoln and Mercury cars. We only read the NHTSA summary. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
