DTC P1102: Mass Airflow (MAF) Sensor Inconsistent With Throttle Position Sensor, Less Than Expected: Condition

DTC is set if input voltage from MAF sensor is less than expected (less than .7 lb/min) for 5 seconds when throttle opening angle is less than 50 percent and engine running. This is a continuous monitor. MIL is illuminated when Powertrain Control Module (PCM) detects malfunction during 2 consecutive drive cycles. Possible causes are:

• MAF sensor malfunction.
• TP sensor malfunction.
• Corrosion or voltage drop on signal circuit.
