So im driving at night from work and i drive from a low elevation and climb to a high elevation and my check engine light kicks on. the car is completly stock right now had my stock tune put on for winter and i get a p0107 both nights in a row and today i even deleted the code before i drove home today and i got the same code today. car drives fine and pulls fine just a bright orange cel smacks me in the face.

 

A P0107 DTC is set when the PCM sees that the MAP signal voltage is less than .25 volts which is too low.

Causes

The causes of a low MAP sensor signal circuit (P0107) could be any of the following:

Bad MAP sensor
Open or short in the signal circuit
Open or short in the 5 Volt reference circuit
Ground circuit open or shorted
Bad PCM

 

so why when i delete it it goes away then comes back i had 2 map sensors go already and when the map sensor went before the boost guage on my rpd wouldnt read anything. when i actually asked on star they told me it was a p0106 but when i look in the code reader it said p0107 what the ****

 

The PCM looks for any change in manifold pressure to be preceded by a change in engine load in the form of changes in throttle angle, engine speed, or Exhaust Gas Recirculation (EGR) flow. If the PCM doesn't see any of these factors change while detecting a rapid change in MAP value, it will set a P0106.

Causes

A P0106 could be caused by:

Bad MAP sensor
Water/dirt intrusion affecting MAP sensor connector
Intermittent open in the reference, ground, or signal wire for the MAP sensor
Intermittent short in the reference, ground, or signal wire for the MAP sensor
Ground problem due to corrosion causing intermittent signal problem
A break in the flexible air intake duct between the MAF and the intake manifold
Bad PCM (do not assume the PCM is bad until you've exhausted all other possibilities)

 

but why did onstar tell me p0106 but when i actually look on a code reader said p0107
