Possible Causes

Possible causes are:

• Damaged MAF/IAT sensor (P0102, P0103 or P1101).
• Blocked MAF/IAT sensor screen (P0103).
• MAF/IAT sensor disconnected (P0102).
• Contaminated MAF/IAT sensor (P1101).
• MAF/IAT sensor partially connected (P1101).
• Open PWR GND circuit (P0102 or P1101).
• Open MAF/IAT RTN circuit (P0102 or P1101).
• Open VPWR circuit (P0102).
• MAF/IAT SIG circuit shorted to VPWR (P0103).
• MAF/IAT SIG circuit shorted to ground (P0102).
• MAF/IAT SIG circuit open (P0102).
• Sensor connector or harness with poor continuity (P1100).
• Sensor with internal intermittent open or short (P1100).
• Damaged PCM (P0102, P0103 or P1101).
• Intake air leak near MAF/IAT sensor (P0102).
• TP sensor system, possible closed throttle indication (P0102).
