P0532
Hello, I have problem with my 2018 LT. It shows P0532.
0.00 V on A/C high pressure sensor in GDS. 0 V on +5v reference, GND has 50ohms to any ground when checked with multimeter. I think wire is damaged somewhere. Can you send me ECM pinout for A/C high pressure sensor, so I could check wire ? In GDS all +5V references are marked as ok. Fan is always working as effect of p0532 error, a/c of course don't work. A/C if full of refrigerant, compressor relay and clutch work. I have TPMS error too, because of one new sensor, but waiting for tpms tool. I don't think it is connected. Thank you in advance! |

Thank you for reply, but the problem is I bought this car on my own from USA to Poland and have no warranty.

It could be wiring as you pointed out. It could also be bad pressure sensor. Have you tested the pressure sensor?

If you give your dealer the code they can put into the GMVIS system and then print out the trouble shooting steps including the pin outs.
