What to look out for in a failing MAP sensor
A faulty MAP sensor will affect an engine's air-fuel ratio. If the ratio is incorrect, ignition inside the engine will occur at an improper time in the combustion cycle. If severe pre-detonation continues over an extended time, the internal parts of the engine (such as pistons, rods, rod bearings) will become damaged and eventually lead to catastrophic failure. Look for these warning signs:
Rich air-fuel ratio: Look for rough idle, poor fuel economy, slow acceleration and a strong smell of gasoline (especially at idle)
Lean air-fuel ratio: Look for surging, stalling, lack of power, hesitation on acceleration, backfiring through the intake, and overheating
Detonation and misfire
Failed emissions test
Check engine light
A rebuilt engine is much more of a hassle than replacing a sensor, so if your engine is experiencing any of the symptoms above, consider troubleshooting your MAP sensor.
Common MAP sensor fault codes
Here is a list of codes that are associated with the MAP sensor to look for if your check engine light has turned on:
P0068: MAP/MAF - Throttle Position Correlation
P0069: Manifold Absolute Pressure - Barometric Pressure Correlation
P0105: MAP Circuit Malfunction
P0106: MAP/Barometric Pressure Circuit Range/Performance Problem
P0107: Manifold Absolute Pressure/Barometric Pressure Circuit Low Input
P0108: MAP Pressure Circuit High Input
P0109: MAP / Baro Pressure Circuit Intermittent
P1106: MAP/BARO Pressure Circuit Range/Performance Problem
P1107: Barometric Pressure Sensor Circuit Low Voltage
