Low charging pressure on compressor - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Folbjo · 10-30-2021, 05:52 PM

I got an engine error code on my 2013 ZL1 convertible.
The engine light is on and the code indicates too low charge pressure on the compressor.
Deleted the code the first time, but came back quickly.

Anyone have any idea what this might be and where I should troubleshoot?

AC compressor?

As I understood the mechanic, who deleted the error code, it was related to the compressor on the engine.

I will have the error code checked again tomorrow and tell you specifically which code it is.

Low side pressure on the AC, usually a leak..

If it's AC related grab a can dye from autozone and a florescent light bulb..... easy to spot where the leak is.

If this is the current fault, will this fault generate the yellow engine light on the instrument panel ?.

Compressor is, or least can be, the supercharger in Europe.

This is what OBD II said today.
Chose to order a new mass air flow sensor, as well as a new supercharger bypass solenoid valve control.
Then we have to troubleshoot to see if there may be electrical contacts that are not in place, or leaks, before we replace parts?

Yes. Check contacts of sensor and valve, and ascertain there are no shorts. Then if necessary, replace valve and sensor. Then check for codes again.
