C1174,P1111, C1175, and P1603 code in Jaguar Xtype what does it mean? My daughters car had the ABS and check engine light come on. Took it to AUTO ZONE and these codes came up.

remove the air filter housing check the wiring has not rubbed through on the metal filter holder mounting common problem.or water ingress in the engine control module/connector the plugs/on plug coils are also troublesome but 3 on the same bank is unlikely to go bad at the same time good luck

Need to know what engine you have, but P1111 on a lot of Jags means "system pass" so in other words it has passed the self checks!

the check engine loght is telling you that the cpu has found a fault in the management system. If the abs light is on as well that would be a good place to start looking for the fault

My jaguar gearbox light has came up some one help please

P1603: Transmission Control Module (TCM) EEPROM Failure
C1145: Front right wheel speed sensor input circuit failure

The P1603 means that your TCM has probably failed. It may have a loose solder connection or the PROM chip may have come out of it's slot. EIther way the TM needs tobe removed from the car and repaired/replaced by a qualified repair person.

The C1145 is for the ABS and it may be related to the TCM failure. I am not that familiar with the Jaguar ABS system, but that code means the signal from the front right wheel is bad. May be the sensor or the "tone ring"...

Copied directly from a Jaguar forum:

P1111 is not a fault code. It is a special designator Jaguar uses meaning system ready, drive cycles completed after the last fault event. P1000, on the other hand, means system not ready, or drive cycles not completed after the last recorded fault event.

Some OBD II Basics - All P0xxx codes are generic and uniform across all manufacturers and mean the same on every car. All P1xxx codes are manufacturer specific codes. You cannot use a generic code chart to analyze P1xxx codes for a Jaguar.

Next time your car displays an engine fault light, try reading the codes then. If you have a CEL illuminated and the only code read is P1000 or P1111, then you probably have a fault that generic code readers cannot see. Could be a chassis code, for example.

One last thing - Neither P1000, nor P1111 can be erased.

Hope this helps you.

HI. The codes and their respective definitions are below:


P1111 Intake Air Temperature (IAT) Sensor Circuit Intermittent High Voltage
C1145 Front right wheel speed sensor input circuit failure
C1155 Front left wheel speed sensor input circuit failure\
C1165 Rear right sensor - trigger monitoring
C1175 Rear left sensor - trigger monitoring

P0128 is a Coolant Thermostat Malfunction

P1000 shows that the fault code has been reset recently (but this code will not bring the warning light on)

C1175 I think is Speed Wheel Sensor LR Input Circuit Failure or Input circuit failure and could be directly related to your ABS fault light indication.

C1175 ABS/TCCM Anti-lock braking / traction control LH rear wheel speed sensor circuit fault ABS/TCCM to wheel speed sensor signal circuit (FH33-21): open circuit, short circuit to ground, short circuit to B+ voltage, high resistance LH rear wheel speed sensor failure
P1000 is for check not complete after last memory clear , dont worry about it , just stick with C1175 , and most probably it is the sensor wire

When I went outside to start my Jaguar X-Type it was cold outside. I was in a hurry and didn't let the car warm up properly. It jumped a bit then the check engine light came on along with a message that said No cruise control. The no cruise light came off but my check engine light is still on. Any suggestions as to what it may be?
