Hello Scotty my name is Jacob AKA Dragon night I have a 2012 Buick enclave knock sensors p0325 and p0 330 we're on when I bought it took it to the mechanic shop and replace both knock sensors and butterfly clips engine light still comes on the repair shop check the voltage on the knock sensors and the harness voltage checks out correctly the vehicle has 182,000 miles on it I took it to Buick to get it checked out the computer it's been $134 for a diagnostic I told him that I suspect it's the ECM they told me I need to spend $900 on them to run a wire from the knock sensor to the clip part connection to the ECM on both sides sometimes the instruments in my vehicle go haywire for instance driving traction control turns off automatically and stabilization radio shuts off and on sometimes or switches from XM radio to CD player to auxiliary and that's pretty much it I ordered a ECM from flagship one hopefully it will resolve the problem I appreciate your input and your help
Knock sensor codes could appear from something as simple as a bad spark plug or coil pack or partially clogged injector. Why all the drama with the ECM?
I'm just guessing the ECM it's part of the function of the main car components I replace the knock sensors the butterfly clips i clear the code code comes right back
I will change the spark plugs and go from there thank you
I'm just saying that something else is causing the knock sensors to indicate (pick up vibrations and report) and are not necessarily the sensors themselves just doing their job.
Ok thank you
