Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
Hi,It is important to understand that the P0069 is not related to engine conditions at all. It is specifically comparing the barometer sensor to the differential sensor while the engine is off.
Knowing that, we can rule out EGR, vacuum lines, timing etc... they are all irrelevant. This code only cares about if the MDP and the MAF read the same when the engine is not running.So with that all said... what are your MDP and MAF readings with the key on engine off?
No problem, we can pick up this evening then?I would imagine the readings are going to be fairly indicative, unless this is something that comes and goes though it doesn't sound that way.
Great. Just post here when you are ready and I will get with you as soon as I see your post.
No need to reply right now unless there is something else to add.
Thanks.Without a barometer reading we are a bit at a loss, however the MDP readings look way off anyway. They are normally in the 30inHg range (key on, engine off) and should never read pressure (psi).
If you wiggle the wiring around does the reading change considerably?
Is this the same reading with the other/original sensor as well?
