RH Det sensor and MAP sensor codes with restricted performance.

I replaced the coolant line under the supercharger... good news... no leak..

bad news I now have these codes at start up car ran fine and never had issues related to these sensors before. I've gone over the harness and confirmed that the det sensor is connected. The MAP sensor is difficult to get at and was wondering if anyone has more info about getting at it without tearing the whole top end apart again.. sames goes for the knock sensor.

Could the map sensor cause the knock sensor to go off?

what about coolant leaking down onto the knock sensor?

 

The knock sensor has a specific torque value for the mounting. The ECM might have a sanity check algorithm to be able to detect that the knock sensor has not been torqued to spec.

Pictures of the knock sensor show that it is probably potted so leaking coolant would not have any electrical effect on the sensor itself.

 

Maybe a disturbed harness / etc. Have a close look at the electrical guide as it even shows splices.

 

I'm going to start with trying to get at the MAP sensor... I've gone over the harness cleaned connectors and used dielectric grease hoping it would resolve the problem.

 

Alright, just removed the throttle body and found a wire had pulled out of the map sensor connector.. anyone know how to get the pins to pop out of the connector? I've got the red retaining clip out already.

 

I'm hoping for something like this for the Jaguar? Do they have a page or pages in the JTIS?

tight area was great to work in but I managed to fix the connector. Removed the red retaining clip, and was then able to release the connector and push out with 2 small flat heads. Soldered a pigtail to the pin and then soldered the pigtail to the factory harness. used heat shrink to protect from moisture.

No more P1108!

cleared the codes and still stuck in restricted performance. I took it for a ride runs fine but after I got home I pulled the p0328 code. I was really hoping the code would magically go away and was related to the MAP code.

 

I attached 2 photos.. I believe these are the connectors for both knock sensors... If I disconnect the right side and jump it into the left side sensor will it solve the problem temporarily?

 

found this picture and figured out the knock sensors run toward the front not the rear... I must have been looking at the O2 sensor connectors?

I found the culprit another broken wire on the connector again. should have her fixed in 30 minutes.. woohhoo!

On another note I think it might be helpful if we could take a picture of the engine bay and edit it with paint or whatever and label the approx location of connectors for each sensor... If there is one in the JTIS I couldn't find it and it would have saved me days of frustration..!

 

Try the Technical Guides.

 

I found a very useful guide under 303-14b > desc & operation > Electronic engine controls. It shows a picture of each sensor with location.
