REMEMBER
To prevent the replacement of good components, be aware that the following non-EEC areas may be at fault.
- Fuel (quality)
- Basic engine
- Spark timing
This Pinpoint Test is intended to diagnose only the following:
- Knock sensor
- Harness circuits: KS and SIG RTN
- Processor assembly
DESCRIPTION
The Knock Sensor is used to detect engine detonation (spark knock). As a result, a voltage sent to the processor will lead to spark timing retard.
