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.

ok the p1111 code is a system check readiness code...the other codes fuel and air mixture codes....please check the upper breather hose under the engine cover...take a philips head screw driver,remove the cover,,,you will see a hose running from the valve cover to the upper intake...check this hose for any cracks...this will usually create a vacuum leak,and cuase the car to run lean or have too much air and sputter...if you want me to send the code meanings I can but on these cars this is usually the issue...Keep me posted

I have trouble codes P1603 and C1145. What do they mean?

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"...

Check engine light code p1603

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?
