This code is for the MAP sensor. It sets when excessive voltage is sent from the MAP sensor to the computer. Most common correction is to replace map sensor, however, it could also be caused by a bad computer or wiring issue

Check your TPS ( throttle position sensor) and MAP (manifold absolute pressure) and change your fuel filter

depending on which side of the engine it is on it could be your map sensor your mass airflow sensor are they vac. lines or electrical wires their are several vac. hook ups that could have three pins on them. is your check engine lite on if it is retrieve the codes and this could give you a closer idea

map sensor control fuel delivery and ignition timing.the map sensor is your load sensor when engine closed throttle high vacuum wide open throttle low vacuum.need more fuel and spark.when your engine at wide open throttle. low vacuum.cause electrical volts to increase to 5 volts in which pcm will increase fuel pressure and spark.the map sensor does control spark also.replace map sensor erase code and see what happens.

It could just be a bad signal from the MAP sensor or a poor connection at the sensor. Or a bad MAP sensor itself. Maybe the vacuum line is off or broken.

Manifold Absolute Pressure (MAP) sensor measures the changes in the intake manifold pressure which result from engine load and speed changes, and converts this measurement into a voltage output.

A closed throttle on when the engine is decelerating would produce a relatively low MAP output, while a wide open throttle would produce a high output. Manifold absolute pressure is the opposite of what you would measure on a vacuum gage. When manifold pressure is high, vacuum is low. The MAP sensor is also used to measure barometric pressure under certain conditions, which allows the PCM to automatically adjust for different altitudes.

The PCM sends a 5 volt reference signal to the MAP sensor. As the manifold pressure changes, the electrical resistance of the sensor also changes. By monitoring the sensor output voltage, the PCM can determine the manifold pressure. A higher pressure, low vacuum (high voltage) requires more fuel, while a lower pressure, higher vacuum (low voltage) requires less fuel.

A high or low voltage fault in the MAP sensor circuit should set a DTC P0107 or DTC P0108. If the MAP sensor sends an intermittent zero voltage signal to the PCM, a DTC P0106 will set.

Hello! I just read your second post...I sent a solution from information in the first post not knowing there was a second...

The culprit is the Manifold Absolute Pressure (MAP) sensor...
It is called the "fuel boss"...Loss of signal will not allow injectors to fire...Crank the engine...With the connector in place you should read greater than 1 volt...No voltage out of MAP...It is defective...Cost is around $60...

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

your MAP sensor is receiving a High Input. possible causes are as follows: this means that the circuit is open or shorted to the VREF, the grounding circuit is open between the sensor and the PCM, the sensor is damaged, PCM has failed. possible causes for the sensor to fail, extended engine cranking or a backfire. I hope this helps you, thanks

make sure you have ngk or ac delco iridium plugs installed. Also common problem on the 2.2L ecotec is the cat plugging. Easy check is to remove the front o2 sensor (very easy 22mm wrench) and start the car and rev it. If it revs freely now and does not bog the cat is plugged. They are covered fed. emissions warranty 8yr 80k, all gm dealers stock the cats for the 2.2 ecotec.

sounds to me you have a emissions problem check your EGR valve and MAP senser
