Get codes p0068 and p0108


codes p0068 refer to Manifold pressure sensor/mass air flow sensor--throttle position correlation--causes ---wiring---map sensor---maf sensor--mechanical fault.
code p0108 refers to manifold absolute pressure(map) sensor/barometric pressure (BARO) sensor--high input. causes ---wiring short to positive---map sensor---baro sensor---ecm.

DTC Code P0107


P0107 -- CONTINUOUS
Continuous diagnostic trouble code P0107 indicated barometric pressure out of range low was detected during normal operation.

Possible cause
- faulty internal BARO sensor (PCM)

Perform KOEO On-Demand Self Test.
Is P0107 present?
Yes, REPLACE PCM. CLEAR DTC and RETEST.
No, P0107 is intermittent fault. CLEAR DTC. If DTC reappears, REPLACE PCM.

If you keep getting it, a new PCM is the only fix.

Po108 service code


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
