Ds5 No A/C even after replacing pressure sensor

[xantia_v6]

I have Lexia/Diagbox, so have not needed to look for alternative systems, but someone else should be able to help with that.

after diagnosing the car today at the dealer next result came out.
error code P0532(signal pressure sensor) short circuit to ground or open circuit. Now I have to measure everything. any advice would be really apreciated. they gave me all the wiring diagrams but still very challenging.

AC FINALLY WORKING
2 connectors where not making proper contact. Both from pressure sensor and compressor.

Well done, great to find and cure the problem.

This seems identical to what I am experiencing now.
I ve recently changed my compressor . I thought my original one was gone, it only had a burnt clutch coil. Anyway...

My AC now is totally stopped , But it was behaving just like what you described. Even the 1.3 volts reading, and the pressure sensor code "shorted to ground":
My clutch would sometimes kick in, but the fan would not turn, and the ac not cool. i changed the resistor of the fan and no change. I cleared the codes as much as possible with the faplite app.

I suspect now the variable solenoid from the compressor may be the culprit.

I saw your conclusion, and your issue was only plugs poorly connected.
Was there any more detail to it? Did you replace anything? why it was marking 1.3 volts. etc.

I appreciate any help.
