Jaguar OBD2 codes

P0100 with lack of power

Supported by vehicle data

Jaguar bulletin SSM73671 covers a lack of power and restricted performance with P0100 on some Jaguar models. The NHTSA summary gives no cause, so check the air intake and sensor 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.

• P0100: Mass or volume air flow sensor circuit fault

P0447 from water or ice in the leak test pump filter

Supported by vehicle data

Jaguar bulletin JTB00436NAS1 says water or ice thrown up by tire spray can become trapped in the DMTL pump filter on 2010 to 2015 XJ models, setting EVAP codes including P0447. 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.

• P0447: EVAP vent control circuit is open (no proper signal from the vent valve circuit)

P068A from a PCM software error at shutdown

Supported by vehicle data

Jaguar bulletin JTB00471NAS1 attributes P068A to a PCM software error during vehicle shutdown on the 2015 to 2016 XF, and says the normal diagnostic index actions do not resolve it. Check for a PCM software update before replacing parts. 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.

• P068A: Engine computer power relay switched off too early

P0736 with harsh shifts in reverse

Supported by vehicle data

Jaguar bulletin 30709 describes harsh shifts and a warning lamp with reverse selected and P0736 stored on the 2003 S-Type. We only read the NHTSA summary, not the bulletin itself, so it does not tell us the cause. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

• P0736: Reverse gear ratio is wrong

P0A40 returning on a Jaguar I-Pace

Possible — needs testing

A 2020 Jaguar I-Pace owner complaint on NHTSA quotes a dealer note for P0A40, a drive motor position sensor range or performance fault, that keeps returning on a car that arrived dead. No bulletin was found. The source is a single owner report, and it needs testing to confirm the cause.

• P0A40: The control module sees the position sensor for drive motor A reading out of range or not matching the motor

P1722 read as stall speed with a transmission quote

Possible — needs testing

An owner complaint on a 1998 Jaguar XK8 says a dealer listed P1722 as stall speed with a gear 4 out of range code, and quoted a replacement transmission. The source is owner reports and it needs testing to confirm.

• P1722: Estimated vehicle speed signal fault in a Nissan automatic or CVT; a different stall speed fault on Jaguar

P228D with rough running or misfires

Supported by vehicle data

Jaguar bulletin JTB00410NAS1 and the matching Land Rover bulletin list the check engine light with P228D and another code, with rough running, hard starting, rough idle or misfires. The summary does not state a repair. Note which codes are stored together. We read only the cached summary, and we have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.
