Hi Guys,
Getting a MAP/BARO Circuit Malfunction code popping up on CEL when I run a code reader, if I clear it returns after 60-80 miles of hwy driving. Any suggestions or ideas.
Thanks

What is the P-code number? Descriptions off of a generic reader or look-up table are not always accurate for Jaguar.

 

Hi, the code is P0105. The code reader I am using is a innova which includes a section for Jaguar, although I think this one may be a generic code. I have tried to clean the MAF with sensor clean but the code returned.

I am assuming you have a 2000 XKR.

It is the MAP (Manifold Absolute Pressure) sensor fault. Do not confuse this with MAF which is the Mass Air Flow Sensor.

The MAP sensor is a small sensor with a single vacuum hose and 3 wires. First thing to check it whether the vacuum hose fell off or is leaking. It could be in the center near the firewall (likely on North Amercan cars) or in the ECM compartment near the firewall.

 

WhiteXKR.
I checked out the MAP sensor on the firewall and the vacuum tube had come loose, hope that fixes to code and CEL.

Thanks
Brian
