In this video we are
In this video we are working on a Chevrolet truck that had it stored code p0332 and stored code p0327 for knock sensor circuit low input for Bank 1 and bank 2.
Knock Sensors and Harness: https://amzn.to/2IuIgsq
I briefly go over what goes wrong to cause those diagnostic trouble codes to set for the knock sensors and also what the repair entails and what the service bulletin is wanting you to do to prevent future failure of the knock sensors.
Labor to replace a knock sensors on the Chevy truck is about 2 hours.
Vehicle is setting a DTC P0332 and P0327 for low or insufficient knock sensor activity from sensor 1 and 2.
Average Reported Mileage: 338036
Tests/Procedures: 1. Disconnect the Blue Powertrain Control Module (PCM) connector and check resistance value on Light Blue wire at pin 11 for sensor two and Dark Blue wire at pin 51. Both of these should be on the Blue PCM connector. The value should be 93K to 107K ohms.
2. If resistance is low, check circuit for shorted wire or shorted sensor.
3. If resistance is high, check for corroded wire or poor connection at the knock sensor.
4. Use an AC voltmeter and check the Hz on each wire listed above while tapping on the engine block.
WARNING: Do not tap on any plastic engine components.
5. While tapping on the block, the frequency on the meter should go over 125 hz.
