The check engine has come on twice in the past two weeks and the code read (knock). The engine has always made some noise from a piston slap but the light has never came on before. Now,I am wondering if I have an engine problem.
My forester severly hesitates then suddenly speeds up my check engine light does report back the knock sensor, does the symptoms sounds related to the sensor?
Check engine light on due to failed knock sensor and catalytic converter
CHECK ENGINE LIGHT HAS BEEN ON FOR 10 YEARS. REPLACED OXYGEN SENSOR TWICE AND KNOCK SENSOR AND TIRED OF REPLACING THEM. SO, IT NOW HAS 175,000 MILES ON IT AND KNOCK SENSOR STILL NEEDS TO BE FIXED. SICK OF FIXING IT. WISH THE CHECK ENGINE LIGHT WOULD JUST BURN OUT.
check engine light on, OBD-ll code P0328 knock sensor circuit, high voltage input. bought part online and will install myself
Check engine light came on and the diagnostic code indicated bad knock sensor, located knock sensor and removed, founf it had a cracked housing. Replaced knock sensor and reset code. Now have 160,000 mile with no further problems.
CEL came on, seemed to run rougher, my mechanics put it on tester, drove it & report all was well after testing/driving- reset CEL. Cel came back on within a week, cruise control lights also flashing/disabled, mech says bring it by in am, hook it up & see if anything else involved. We shall see....
I had this same issue and reported it as well, but took it the shop and replaced the sensor as well as did a full tune up..All belts, Wires, Plugs and fuel filter and that fixed my check engine light as well as the A/T temp light
they cannot seem to fix it
check engine light on dealer checked an came saying is the knock senser
knock sensor failed but good sensor havent fixed yet
Check engine light came on. Then off. 2 weeks later it came back on and stayed on. It's at the dealership now, parts and labor $352. I'm researching right now to see the cost of the part and how to do it myself.
It appears to be about an $8 part. And it may be slightly difficult to replace it myself without the tools. Looks like I need a extended socket wrench.
My knock sensor failed and check engine light turned on. Fixing issue.
Check engine light was on and I discovered that it was the knock sensor. I replaced the sensor and even though I can hear slight detonation knocks, it is doing just fine after about a year.
CEL came on as knock sensor reading low. Changed knock sensor with a aftermaket (Bosch I think) and CEL went off and trouble code never came back.
