Review on ๐Ÿ”ฅ 213-3521 ACDelco GM Original Equipment Ignition Knock (Detonation) Sensor by Jason Cho

Revainrating 1 out of 5

Avoid junk good for detonation

I bought these a year ago and they were in the store. Spent 4 hours 3 days on this repair. First, one of the sensors wouldn't screw in, so I bought a new one at a local store. Yesterday my Tahoe threw away the code on the knock sensor I bought from this company. I know because I put it in bank 2 and that's the code I get. On Saturday I will again do all the repairs to replace the brand new knock sensor from this company. I don't enjoy disassembling half an engine 2 days in a row. I knew I should never have installed it after the first one was junk.

Pros
  • Great price
Cons
  • Almost never
