Mechanic's Assistant: Which particular sensor are you asking about? And have any trouble codes been triggered? Map sensor code p0069 Mechanic's Assistant: What is the make/model/year of your car? 2014 Mitsubishi Lancer evolution GSR Mechanic's Assistant: Are you fixing your Lancer Evolution yourself?

Hi, my name is Jay Do you have the turbo engine?

i do
Automotive Expert
Have you replaced the Barometric pressure sensor? The code is a lack of correlation between the BARO and MAP sensor and you already replaced MAP so the only thing left is the BARO sensor.

I don't seem to find that specific sensor for my car
Automotive Expert
It is built into the Mass airflow sensor.

I have not changed the maf only tried cleaning
Automotive Expert
When you first turn the key to on before starting the computer compares the MAF and MAP and they both should give same Barometric pressure reading and one or the other sensor is wrong. Since you already replaced Map then the MAF must not be giving proper reading.

this could be causing my high idle ?this could be causing my throttle body to stay open?
Automotive Expert
What do you mean staying open? It may cause running issues but if throttle is sticking open I do not know if it would but can cause idle high or low issues. Also can cause lack of power or running rich or lean.

The computer diagnostics i ran said the throttle was opening or staying open ... after driving for a little when at a red light or I'm neutral the RPMs will creep up to maybe past 2k then come back downIs it possible a sensor can be getting the throttle body to act funky
Automotive Expert
Yes it can but If throttle body is having issue then it most likely set a code like the code P0069 you get is for MAP an MAF. Is P0069 only code you get????

only code that has came about
Automotive Expert
Then I would concentrate on repairing active codes and then see how it runs. Also make sure to check rubber tube between throttle body and MAF for any cracks or loose clamps. Any other questions for me?

Ok i will try a new MAF out and give it a shot thanks
Automotive Expert
Your welcome.

Still not sure what you need?

Have a certified mobile mechanic diagnose what's wrong with your car, at your home or office.
