What's this fault code

Post by stu9 »

03 C5 2.0 hdi

I got code P2022 after Googling it I got this....I tried to copy/paste but for some reason it wont right click to do it :roll:


"intake manifold runner position sensor/switch circuit high"

Anyone know


Edit...what I should say...a few days ago, I changed black plastic throttle butterly valve thing that bolts onto the top hose....I wonder if it's faulty and giving the code, I'll put mine back on

It's great how you can put a code up and no bugger answers :|

By "changed" what do you mean - fitted a second hand unit or new genuine? Metal or plastic butterfly?

You're not using Lexia. It gives situational parameters, sort of a "freeze frame" of when the fault actually occurs.

Not that it's terribly useful half the time.... on the first Lexia read of my Xantia and a C5 I recently diagnosed the additional data logged with the fault code was largely meaningless and nonsensical - for example on the C5 it was claiming that the clutches had slipped on the gearbox when the ambient temperature was -50 degrees! Yes, minus. :roll: Considering that the fault code was logged minutes earlier and the temperature sensor on the gearbox was quite alright thank you, it seems that the fault code logging software in the ECU's was not tested terribly well during production...

I would take any additional data logged with a fault code even on a Lexia with a very large grain of salt.

Lexia is quite useful; the phantom faults are mostly easily diagnosed (ie, dismissed) once you appreciate the causes of irregularities in data production on the car. It's a tool for mechanics and that's where the additional learned skills or insight will enable one to make sense of a spray of faults.

There's also non-logged events that affect running, some refer to them as upstream faults. Collapsed alternator diodes r shorted cooling fans being a couple of good examples. Neither will cause an accurate or specific fault to be logged, but both can bring about stumbles, misbehaviour and general automotive malaise that the hoi polloi have no joy in making sense of.
