Engine/Transmission (1998.5 - 2002) Turbo boost gauge quit working

[thouse]

I get a code po237, Turbo/superboost sensor a circuit low. Anyone know where this sensor is located. My boost gauge also stopped working, but it still runs great.

The MAP sensor detects boost pressure.



Go to this link and look at #8:

Occasionally a fueling box will cause this error code to be set. After three starts the error should dissappear if all is well. Otherwise, you may have to disconnect your box if it has a problem.

Thanks, I changed the fuel filter a few days ago and if I am lucky maybe just a loose wire.

Could be a loose wire. While checking it, clean the contacts and use some WD 40 to help keep out moisture.

I pulled the wires, and put dielectric silicone on the contacts. The boost gauge works now. I do not have a check engine light, but still have a code with the OBD reader. I did some additional reading and it is in the Alex Peper software.

Thanks again
