I drive a 1999 Jaguar Vanden Plas. I have been getting a P0455 reading on my OBD Scanner - EVAP Emission Control System Leak. I also have not been able to get my car to pass inspections do to emissions. Does anyone have an idea of what I will have to do to get this fixed? Details would be very helpful.

Here is the list a Jaguar technician would start with:

 

FinAdviser: The P codes are manufacturer specific, and P1637 on a Jaguar is a ABS/TCM CAN fault. The P1637 code can be a simple fix--or very complicated.

It can be a CAN cable problem to the ECM, an ABS sensor or module problem, a ECM problem, a DSC problem or a TCM problem. A Brake stop switch is another notorious cause of ABS lights. Wiring problems can be cut wires, shortages, polarity problems, connector pins bent/shorted out . . . .

My gameplan: 1. New brake pads and rotors (needed anyway) 2. Clean the ABS sensors, 3. Inspect wiring to ABS Sensors for fraying. 4. Pull the ABS module and solder the two places on circuit board 5. Replace the Brake stop switch ($70). If problem not solved by then, I'll take car for full OBDII/CAN diagnosis.

I see that you've asked for help on a number of postings for a number of other OBDII problem codes. You might get more assistance if you put them all on one posting, as some problems might be inter-related

 

FinnAdviser,

I've merged your multiple threads into one and deleted the duplicate post in General Tech Help.

I believe you will get the best response here.
