Knock sensor - 22 CEL - Cost?
Hi !
I have a MY00 and have recently had an 22 CEL code coming up every now and then. From what I have read this is a knock sensor code. Before this code started appearing the car was also stalling and idling very low - sub 500rpm) My car has some basic mods - unichip-3" turbo back exhaust- vf23/4-PWR TMIC. I used to get the car tuned by Brett at PSi but that cant happen anymore, so I took the car to Tim Slacko. He proceeded to retune the car and tell me how much brett had stuffed up the configuration of the unichip and charged me about $400 and also replaced the leads. This fixed the idle problem somewhat, it still is to low and lumpy. Then the error code started coming up, so I took it back. He couldn't fix, so now I am wondering is it as simple as replacing the knock sensor? ATM car drives fine when the Check engine light isnt on, but when it comes on which is now most of the time the car will not rev smoothly to redline, it splutters at about 6k-7k. I have tried clearing the codes, always comes back as a 22 CEL. Any help would be great Thanks Jamie |

I just bought a knock sensor for my GT on monday. It wont be the exact same part but Id image the price to be the same. mine was $142.50
Its easy to replace. All you need is a 12mm socket and the sensor is located just under the throttle body and a little to the right. You'll want to remove the TMIC or FMIC piping to get at it easy.

Make sure to reset the ECU after the knock sensor is replaced.

I just put mine in a couple hours ago now. My old one had a nice big crack running through the outer casing and was making it overly sensitive. Because of that, I was getting up to 7 degree of ignition retard coming onto boost. Fucking sucked.
But now, new knock sensor and ECU reset, I dont get any more ignition retard anymore normally. It went up to 1 degree of retard when I was giving it an extended boost going through all the gears a few times and the intake temps went above 35C. All good. Im very happy and my lost power has been restored.

How did you measure seven degrees of retard or is that more a figure of speech?
