  • Warning Light on the Dash. What Does it Mean?

    Today's cars and trucks have many lights that can come on the dash to warn the driver of a problem in a particular system. Many times when multiple lights are on, these can be related to the same problem.

    Computers "TALK" to each other. So, a problem in one system can affect one or more other systems. Sometimes this will cause a system to be dissabled and the warning light to come on, even though that system does not have a probem.

    A good example of this is that a problem in the ABS will usually cause the Traction Control to be dissabled. You may have an indicator that shows "TRAC Off". That does not neccesarily mean there is a fault in the Traction control function.

The power steering fluid reservoir holds the power steering fluid and may be integral with the power steering pump or remotely located. The following locations are typical locations for the remote reservoir:

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.
