Saturn: Burning Smell From the Front of the Vehicle

Burning smell SaturnModel: 2003 Saturn L300, 3.0L

The customer states there is a burning smell coming from the vehicle.

Cause
Confirmed the customer’s complaint and found there was a burning smell coming from the vehicle. The smell seemed to be originating from the dash area. Road-tested the vehicle and found the speedometer was intermittently inoperative. Removed the instrument cluster for a closer inspection and found the burning smell was coming from the speedometer. Removed the speedometer from the cluster and found the circuit board was melted, which confirmed the speedometer was faulty and the cause of the burning smell.

Correction
Replaced the speedometer and verified the vehicle operated properly. The customer’s concern did not return.

Detecting Misfire And Knock Conditions

Knock sensors are mounted on the block near the base of the cylinder head.

The knock sensor is a piezoelectric accelerometer that acts as a microphone on the engine. It converts vibrations into alternating current (AC) signal. When the crystal inside the sensor is vibrated, it produces an AC voltage. The greater the vibration or shock, the higher the voltage and frequency.
