Dear Sir,

my problem is (check engine light on), after Computer test appears code P0106.

I read about P0106 code that mean a problem in manifold absolute pressure sensor (MAP).

So car mechanic told me to change the EGR sensor, I purchased original from Ford Motor Company. And we reset and deleted all codes, but still check engine light on
and code P0106.
we test transmission wires from EGR to Computer all was good.

So what is the problem?
where is the problem?

car mechanic told me to change Mass Air Flow (MAF) sensor. Another told me no.

one mechanic told me to change the car computer? Another told me no.

car mechanic told me in my vehicle there no MAP sensor. If he is wrong where can I found the (MAP sensor) for my vehicle?

Please help me in my problem.
Thank you

P0106 - Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem

It would be less expensive to just let one mechanic diagnose the problem and repair it. It sounds like they are giving you their best suggestions based on never looking at the vehicle. That is like expecting a doctor to prescribe a treatment plan when he never saw you.

This fault code should be real easy to verify while watching live data on a scanner. MAP sensors measure intake manifold vacuum. This code indicates the sensor is sending signal voltages that are wrong, but are still within the acceptable range. There are other fault codes when the signal voltage is outside the acceptable range.

I do not know why anyone would have you replace random parts in other circuits that have nothing to do with the MAP sensor. The whole point of having diagnostic fault codes is to indicate which circuit needs further diagnosis. The MAP sensor itself could be responding too slowly. Older sensors were connected by a vacuum hose. That hose could be leaking or blocked. The readings could be affected by some other vacuum leak.

They told you the wrong sensor, maybe due to a miscommunication. He probably meant EGR module which is on top of module. May be the cause.

I go to three mechanics and many diagnoses. No good help. And I pay too much!

NOW :

1: EGR new (changed from three days).
2: transmission Wires from EGR to computer all was good.
3: codes clear and reset.

But still P0106 code and check engine light on.

Where is the problem?

1:vacuum hose?
2: MAP sensor?
3:(MAF) sensor?
4: the car computer (engine control module) (ECM).

Can you show me in picture which vacuum hose you mean?
Can you show me in picture where is the MAP sensor in my vehicle?

Really I need a good help. Please!

It is not EGR, it is the EGR module and you need someone to do what cardiodoc says.

Third from left on top.

Upon further searching, it appears this engine does not use a MAP sensor. That would explain why there is so much confusion concerning this fault code.
