Condition

Some customers may comment on a mild to severe engine ping (commonly referred to as spark knock), usually worse during acceleration and/or an illuminated MIL. Upon investigation, the technician may find DTC P0332 set.

Cause

This condition may be the result of corrosion of the rear bank knock sensor due to water intrusion into the sensor cavity. This condition is more apparent on vehicles in which customers frequently wash the engine compartment.

Correction

Replace the rear bank knock sensor and build a dam (wall) around the sensor using RTV to divert water away from the sensor. Use the procedure and part number listed.

1. Remove the intake manifold. Refer to the Intake Manifold Replacement procedure in the Engine Controls sub-section of the appropriate Service Manual.

2. Remove the wiring harness assembly from the knock sensor.

3. Remove the rear bank knock sensor.

4. Install the new rear bank knock sensor.

Tighten

Tighten the knock sensor to 20 N.m (15 lb ft).

5. Install the wiring harness assembly to the knock sensor.

6. Apply a bead of RTV silicone sealant approximately 9 mm (3/8 in) wide and 6 mm (1/4 in) high along the outside edge of the ridge on the engine block valley cover around the rear bank knock sensor. DO NOT form a complete circle. Leave the rear section open as shown.

7. From the underside of the intake manifold, completely remove the rear intake manifold seal (foam material).

8. Install the intake manifold. Refer to the Intake Manifold Replacement procedure in the Engine Controls sub-section of the appropriate Service Manual.

 

BTW, this TSB also applies for code PO327.

If you're just doing an intake swap, and haven't thrown the codes yet, you should do this as a preventative measure.

 

I think this belongs in here as well.

I hope this helps show the grinding locations or if you take a chisel to it. Good luck!

 

I watched the video and its gonna be alot of help for when I do the intake swap. (Good Job Blueknight) I noticed instead of doing the coolant crossover pipe, the ribs were chizzled off on the ls6 intake before being installed. My question is... If im gonna use the fast 92 intake can I do that? Or do you have to buy the ls6 crossover pipe? Thanks

 

I don't know, you may need to do a search or start a thread.

 

i cant seem to get the video player to even load... I just get a blank white space where the player would be..... are these vids on youtube or anything more standard (who uses myspace anymore.... =P) I'm thinking its just a filter at work thats not letting me watch this though.

 

It is most likely your work filter. No one else is having a problem. I used myspace because youtube and streetfire.net said my files were corrupted. I apologize for any inconvenience.

 

I'm a complete noob trying to replace the knock sensors, I already got the two sensors and the harness ready to install, I found this thread searching the forums, i just have to thank BlueKnight for the video, its so helpful... whats this thing I think I broke? is it the oil sending unit? where can I buy a new one at?


also what can I do to prevent this?, that can't be good for the wire


and can I reuse the gaskets or get new ones? any help and tips re instaling the manifold please anyone

 

i was cleaning my iac just a couple days ago and i thought back to this video and went hey ive never seen my iac move so i cycled the key while it was out and my cap and spring wound up flyin out lol took me forever to find them too i had the tractor in the garage and the car was behind the garage in some tall grass

thanks for the inspiration bro lol

 

It's your oil pressure sensor. You can pick one up at a dealer for about $100 or get lucky on ebay.

 

Get new ones. It's $20 and well worth it.

 

OK thanks guys, oil sensor is $35 on eBay, I hope I don't break it when I put everything back

 

Bump for making a sticky

 

This is already a sticky. Thank you though!

 

Wheres the video of your transAm running with all the new goodies on it?

 

AWSOME material !! .... duuude can you please show the chezeling the intake's plastic stuff in a clear diagram or help post the picture you talked about in the vid ....

I have read anywhere from 5-15RWHP depending on other mods.
