Ok wingers, I got a code 26. swapped the knock sensors and got code25. this is supposed to verify a bad sensor. Replaced the faulty sensor and still getting code. Do I have to clear the ecu some how?

That does indicate a bad sensor. Sure you replaced the faulty one?

If your fault followed the sensor, you replaced the sensor and now you have a fault that follows the new sensor......must have received a defective new sensor.

To clarify may I ask what sensor did you replace with a new one? Left or Right?

Which code keeps back?

It sounds like the ECU is the reason for the fault. There has been a rash of these faults lately where the Knock Sensor code has been thrown but the end result on every one was a bad ECU.

How can a bad ECU call out a left sensor and when moved to the right side the ECU calls out the right sensor? Wingrider69, did you move the new sensor to the left side and test again??

IF,
you are still getting a bad code, and if you indeed swapped the sensors to the opposite side and got a different code, it is NOT the ECM.

a "new to you part" is not always " a good working part ", so get another ' new sensor '.

Well to make sure, I switch them back. To test if memory serves me, raise above 2500 RPM , 10 seconds... to have the ECM test for active knock sensors.

Mine when tested, showed 59-60 hertz at the ECM connector both left and right. I Tested the actual sensor and wiring... together.

If you have a Frequency capable multimeter you could try that. Back probe the knock sensor wire at the ECM connector, raise the rpm above 2500 and measure the Hertz.


Switching the actual sensors to make sure the fault code stays on that same side ... kinda confirms the issue, it’s the ECM or the wiring or actual connector at the knock sensor.

Wish you luck

Is the Oxygen and Knock sensor one in the same? You are showing multiple listings for Oxygen sensors.

no, they are not, I goofed.
only look at the Knock Sensors, I will edit out the wrong ones.


this time, looking for 'knock' only got 2 hits.
