Knock Sensor problem - 6G Celicas Forums

Topic #90643 1 posts Started by yagamius
Hi All

When I rebuild the Engine unfortunately I broke the original knock sensor frown.gif and from that day on I've had change 3 knock sensors and the problem still coming up. If I keep a steady 2800 or 3500 RPMs the engine light came up and the car looses power and become a thirsty gas drinker, I have to reset the ECU to get back to "normal".

Don't know where to start to find out what the problem might be. After the rebuild something happen and a ground went off near the ECU and the car wont start, an electric guy help me found the problem and the car start again, no damage to the ECU were made by this.

One of the knock sensors is brand new from Dealer last Thursday. its a ST 94
