Candidate cause (the documents say what to do)
Rear bank knock sensor corrosion from water intrusion (P0332)
Customers may report mild to severe engine ping (spark knock), usually worse during acceleration, and/or an illuminated MIL.
The technician may find DTC P0332 set.
How to tell
P0327P0332Check engine / Service Engine Soon
What to do
- If P0327 and P0332 set at the same time, inspect for poor connections at the two-wire knock sensor harness located at the left rear side of the intake manifold near the top, just under the cover.
- Check the resistance of the knock sensors including the harness before reinstalling the intake manifold.
- Replace the rear bank knock sensor and build an RTV dam around the sensor to divert water away from it.
Caution: Do not form the RTV into a complete circle; leave the rear section open.
