Has anyone ever had to replace their MAP(Manifold Absolute Pressure) sensor? And if so, what problems were you experiencing??
I'm suspecting mine is bad. If you've read any of my last posts, you'll know that my car died on Friday, and hasn't started since.
I'm getting really frustrated with regards to my ECM though. It has NEVER given me a SINGLE OBD Trouble Code!! My Coolant Temp. Sensor went, my O2 sensor went, my EGR valve went, etc...and NEVER a single code!?? WTF??
I've read that a MAP can cause: no start, hesitation, erratic idles, fuel starvation, etc...but just getting the general consensus with you guys...
Correct me if I'm wrong with this:
The ECM, with regards to some things, OUTPUTS commands/data, and with others, gets INPUTS, correct? So an ECM commands how long the fuel injectors stay OPEN, but cannot command the MAP sensor to be at a certain value, right? And vise-versa, the ECM cannot get any INPUT from the fuel injectors, but does get INPUT from the MAP sensor, correct??
If it isn't my MAP Sensor, which I'm "hoping" it is(it's cheap and easy), than my next guess would be my ECM.
If you guys haven't read my last messages, PLEASE DO!!
