P0108 is the code for a problem with the MAP electrical circuit sensor having too high voltage input to the Engine Control Unit (ECU).
How do I fix code P0108?
Zitat von Youtube: Either next to or on the throttle body itself first carefully remove the map sensor from the engine inspect the map sensor for any damages. If the damages are found then replace the map sensor.
What causes low voltage MAP sensor?
The MAP circuit for low voltage problem may have several causes: The source of the problem is the sensor range voltage input is less than required by the ECU. The most common problem is a bad MAP sensor.
What happens when MAP sensor is faulty?
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.
What are the symptoms of a failing MAP sensor?
Signs of a Broken MAP Sensor
- Poor Fuel Economy. If the ECM is reading low or no vacuum, it assumes the engine is at high load, so it dumps in more fuel and advances spark timing. …
- Lack of Power. …
- Failed Emissions Inspection. …
- Rough Idle. …
- Hard Starting. …
- Hesitation or Stalling. …
- Check Engine Light.

What causes a P0108?
Code P0108 sets when the voltage to the PCM from the MAP/Baro Sensor Circuit stays above 4.5 volts for 10 seconds or more when the values from the Throttle Position, RPM and Oxygen sensors are changing. A vehicle with this code should be taken in to a repair shop for diagnosis.
Where is the MAP sensor located?
The MAP sensor is typically located on the intake manifold, either next to or on the throttle body itself. (On a forced-induction engine, the MAP sensor can be found on the intake tract before the turbo.)
Can MAP sensor be cleaned?
Use an electric parts cleaner on a soft rag or paper towel to clean the outside of the MAP sensor. Spray the electric parts cleaner into the sensor port — a couple of spritzes are usually sufficient. Shake out the excess and let the MAP sensor dry.
What happens if you unplug a MAP sensor?
With the MAP sensor disconnected, the fuel delivery will be excessive and could cause harm to the engine and exhaust system (catalytic converters). Your vehicle getting on the freeway accelerating, bogging down, and reaccelerating sounds like fuel starvation. It could be a fuel pump fault or a plugged fuel filter.
Can MAP sensor cause transmission problems?
MAP – The Manifold Absolute Pressure sensor creates a signal based on vacuum levels in the intake manifold, which indicates engine load. A faulty MAP sensor can cause late, harsh shifts, early / soft shifts, or even prevent the transmission from shifting at all.
How do you diagnose a MAP sensor?
Zitat von Youtube: Next you grab your multimeter. Turn it on and you want to choose 20 volts on the DC voltage scale next you'll ground your black test lead then remove the connector. That's going to your map sensor.
How much does it cost to replace a MAP sensor?
The sensor itself will cost you anywhere from $30 to $200, depending on your vehicle and if you use OEM or aftermarket parts. If you go to a mechanic or dealership to have the MAP sensor replaced, tack on another $40 to $60 or so in labor cost.
