Diagnostic Code P2074 on 2007 PT cruiser-can't find on OBD list.

What the P0522 code means. The oil pressure sensor sends a message to the PCM (Powertrain Control Module), which gets transmitted in the form of a voltage reading. A vehicle will store P0522 when that message tells the PCM that the sensor is indicating too low of an oil pressure value.

I don't see any online reference to that code: Are you sure it's correct? How did you get it? Most codes for the standard OBD diagnostic system begin with a "P" followed by four numbers. Many auto supply stores will let you borrow a code reader (free) with instructions on how to use it (in the parking lot). It's usually a quick and easy way to check the codes.

Buying a Chilton/Haynes repair manual for your make/model/year would be one of the best investments you could make. It will tell you where the EGR valve is and how to replace it. These repair manuals also have the diagnostic codes. Your vehicle would use the OBD-II code reader.

-----------This will help.Thanks.

have someone read the code with a code reader to see why it is on.

Have a look at this:

http://www.obd-codes.com/trouble_codes/

Are you sure its P2074. only asking because IM having a hard time finding it. If it was P0274 that would of been a injector issue(high voltage) on cyl. #5. if i find anything else I'll contact you.

This doesnt show up for your car and I was wondering if you could either cofirm it with him or get someone else with adifferent brand OBD 2 scanner to pull codes. Is your PT from europe?
