We do not have this make so I can only provide a general description of the codes meaning and poss causes.
P0108 - Manifold Absolute Pressure/Barometric Pressure Circuit High Input

Possible causes- Manifold Absolute Pressure harness is open or shorted
- Manifold Absolute Pressure sensor poor electrical circuit connector
- Faulty Manifold Absolute Pressure sensor
- Faulty Powertrain Control Module (PCM) or Engine Control Module (ECM)

Fault codes daewoopo108
P0108 Manifold Absolute Pressure (MAP) Circuit High Voltage points to a manifold absolute pressure (MAP) sensor that's reporting a continuous low intake manifold vacuum pressure condition regardless of present engine operating conditions. Most likely a bad MAP sensor

I have a 2000 Dodge Durango with 128,000 miles. The check engine light has been on and off the past few days. The OBD II code is P0108. What does this mean?
P0108 - MAP (Manifold Absolute Pressure/Barometric Pressure) Circuit High Input
The MAP (Manifold Absolute Pressure) sensor measures engine manifold negative air pressure. It's usually a three wire sensor: a ground wire, a 5 volt reference wire from the PCM (Powertrain Control Module) to the MAP sensor, and a signal wire that informs the PCM of the MAP sensor voltage reading as it changes. The higher the engine vacuum, the lower the voltage reading. The voltage should range between about 1 volt (at idle) to about 5 volts (WOT wide open throttle).

If the PCM sees the voltage reading from the MAP sensor is greater than 5 Volts, or if the voltage reading is higher than what the PCM considers normal under certain circumstances, a P0108 DTC will set.

Contact us if need additional details; good luck.

Hi,
OBD II Fault Code
  • OBD II P0108
Fault Code Definition
The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold. This provides critical data needed for the Power Train Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, and many components of the Emissions Control Systems. The Manifold Absolute Pressure/Barometric Pressure Sensor converts the Intake Manifold air pressure into a voltage that is high when the Intake Manifold air pressure is high and low when the Intake Manifold air pressure drops to a vacuum. The P0108 code indicates a high voltage input from the Manifold Absolute Pressure Sensor/Barometric Pressure Sensor to the Power Train Control Module.
Symptoms
  • Check Engine Light will illuminate
  • In many cases, no abnormal symptoms may be noticed
  • In some cases, the engine may be hard starting and/or get poor fuel economy
  • In some cases, noticeably poor engine performance may occur
Common Problems That Trigger the P0108 Code
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is defective
  • Intake Manifold vacuum leaks
  • Faulty or corroded Manifold Absolute Pressure Sensor/Barometric Pressure wiring or connections
Common Misdiagnoses
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is an Intake Manifold vacuum leak
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is a stuck-open EGR Valve
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real problem is a defective Idle Air Control Motor, which causes a very low engine idle

I have five fault codes for my GM Safari Van what are they and how can I find out what they mean? P0507,P0122,P0106,P0108,P0122
P0507, Idle Control System RPM Higher Than Expected
P0122,Generic TPS/Throttle position sensor A circuit low input
P0106, Manifold Absolute Pressure barometric Pressure Circuit Range/Performance problem
P0108, Manifold Absolute Pressure ( MAP) Sensor circuit high voltage.

Good luck

I SCANNED MY MALIBU & GOT A P0108 WHAT CAN I DO TO RESOLVE THIS PROBLEM
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.

CHECK ENGINE CODE "PO108" WHAT IS THIS AND HOW TO CORRECT
HI. The code and its respective definition will be located below:

P0108 --- Manifold Absolute Pressure/Barometric Pressure Circuit High

Here are a few possible causes for the high signal transfer of the circuit:

  • Leaking EGR valve
  • Vacuum leaks
  • Dirty fuel injectors
  • Wrong fuel pressure
  • Low engine compression
  • Ignition miss
  • Carbon deposits on the intake valves
  • Valve problems
Check the engine for the above faults. If all the points above check out Ok; Replace the MAP sensor.

06 pt cruiser dtc p0108,p0113,p0123,and p0508 car will not start
P0108 (M)
Manifold Absolute Pressure/Barometric Pressure Circuit High Input
MAP sensor input above maximum acceptable voltage.

P0113 (M)
Intake Air Temperature Circuit High Input
Intake air (charge) temperature sensor input above the maximum acceptable voltage.


P0508 (M)
Idle Air Control Motor Circuit Low
Idle Air Control Motor Circuit input below acceptable current.

THESE DIFNITIONS ARE FROM THE FACTORY REPAIR MANUAL, LOOKS LIKE YOU MAY HAVE A WIRING HARNESS PROBLEM OR DISCONNECTED COMPONENTS, CHECK THE IAT AND MAP SENSOR AN MAKE SURE THEY ARE CONNECTED.
