I threw a new code today, and I'm still getting a MAP sensor code.

P1106 Barometric Pressure (BARO) Sensor Circuit Range/Performance Problem
P1129 Manifold Absolute Pressure (MAP) Sensor Circuit Higher Than Expected

Those are the two codes I'm throwing. I might also have an air leak, gonna see if I can fix that tomorrow hopefully. Is it possible that I need a new BAR sensor with a bigger range? I'm thinking the MAP sensor got broke bc I dropped it a couple times while I was taking the car apart a few months ago. But my mech told me that if there is an air leak that could be causing the MAP issue, could that also cause the BAR issue (I'm thinking yes since a leak would dramatically change the pressure).

 

If by air leak you mean vacuum leak then yeah, that'll throw the sensors off and make your car run like crap.

 

yeah vacuum leak...

 

Ok yeah so I tightened a couple bolts/nuts I thought might be causing a vacuum leak, started the car up and backed it up and put it in first moved forward a bit, repeated, engine stalled and threw a code. Well at least it was not a MAP or BARO code so I think there is no vacuum leak anymore, the code I threw was P0336 - Crankshaft Position Sensor A Circuit Range/Performance. Can anyone help me? Everytime I think I fix one problem another one pops up, I have an appointment to get my UEGO hooked up tomorrow, will the car be ok to drive it over to the shop? or should I get it towed? Really need some help here.

 

Chim have you tried to reinstall the stock parts? See if the codes pop up again?

 

No I have no intentions to, it would cost me more money to attempt to put stock parts back on.

 

Crankshaft sensors tend to go out, I'd replace it and see what happens. The CPS went out on my truck a while back and it caused the truck to die.

I'm glad the vacuum leak fixed you're other codes though.

 

I'm gonna call my family mech monday and see what he thinks (gonna call the dealership and price a sensor, if not too much I'll order it so I can pick it up Monday), bc of the flooding in my area had to pospone my appointment for the UEGO to July 18th. Still working on the DIY, it's coming along nicely, figure I should have it done in a couple weeks; hopefully after I have conquered all the issues that keep arising. Hoping the CPS isn't related to the swap and just went on it's own.
