DTC P0108: Map Sensor Circuit High Input: Condition

DTC is set when throttle is closed, MAP sensor value when engine is cranked is less then when engine is started. DTC is also set when throttle is closed, engine is at normal operating temperature, engine is at 2000 RPM or more and is decelerating, and MAP sensor value reads 38 in. Hg. or more. MIL is illuminated when Powertrain Control Module (PCM) detects malfunction during first drive cycle. Possible causes are:

• Short or open circuit between MAP sensor and PCM.
• MAP sensor malfunction.
• PCM malfunction.
