DTC is set when Powertrain Control Module (PCM) detects input voltage from Intake Air Temperature (IAT) sensor is less than .2 volt. This is a continuous monitor. MIL is illuminated when PCM detects malfunction during 2 consecutive drive cycles. Possible causes are:

• IAT sensor malfunction.
• Short circuit between IAT sensor and PCM.
• PCM malfunction.
