2007 Dodge Caliber
Engine size: 4 cyl
Warning lights: lightning bolt?
Question: Lightning bolt light came on care will not start or take a battery jump.

Answer: This light should not cause the engine to not crank over like a dead battery. But it can cause it to crank over but not start. This light informs you of a problem with the Electronic Throttle Control system. If a problem is detected the light will come on while the engine is running. Cycle the ignition key when the vehicle is completely stopped and the gear selector is in the PARK position. The light should turn off. If the light remains lit with the engine running your vehicle will usually be drivable, however, see your dealer for service as soon as possible or go to Autozone and have them read the codes for you for free. If the light is flashing when the engine is running, immediate service is required and you may experience reduced performance, an elevated/rough idle or engine stall and your vehcle may require towing. The light will come on when the ignition is first turned on and remain on briefly as a bulb check.

    Common Engine Codes

    Intake Air Temperature Sensor (IAT) Code P0112 Or P0113

    The intake air temperature (IAT) sensor is a thermistor which measures the temperature of the air entering the engine. The powertrain control module (PCM) applies 5 volts through a pull up resistor. When the intake air is cold, the sensor resistance is high and the PCM will monitor a high signal voltage on the IAT sensor signal circuit.
