1999 Chevy Silverado Check Engine Soon Light

Mr. Bob take it to the nearest autozone and have them hook up their receiving computer called scantool to extract the OBD2 code/s and comeback with it so we can follow thru.

Thanks for donating we sure appreciate your kindness.

Okay... I went to Autozone and rented (bought & returned) their code reader (ACTRON CP9135). By the way thanks for the advice whoever, on how to rent/borrow a tester.

Code Reader gave back 2 Error codes which were "exactly" the same. 1 of 2 and 2 of 2 both reported:
P0332 Knock Sensor 2 Circuit Low Input (Bank 2).

And yes, I triple checked to make sure that both error codes said Sensor 2 and Bank 2 (not 1 in either case).

The Autozone computer said it could be the following: defective Knock sensor, loose connector, knock or rattle, or low fuel pressure.

I went ahead and erased both codes.

Can someone tell me where and how difficult the knock sensor is to get to and replace (cost is about $42)? Also is there only 1, or 2 on this model truck?
Other ideas?

Thanks, Bob
