Question about 2006 Saturn ION 3

1 Answer

What would cause a p0236 code to continually go off even after knock sensor has been replaced twice?

The knock sensor code (p0236) went off four days after i bought the car so we replaced it and not two days later the code went off again. Thought i had gotten bad gas and that was what was causing the light to come on so I got better gas and fuel injector cleaner hoping that would cause the light to go off but it didn't. Took it back to dealer to have them diagnose and fix, but they got the same p0236 code and replaced the knock sensor as well, but again a couple days later and the light was back on.

Is there a knock in the engine? If the motor rattles, the knock sensor will think its pinging and retard the timing to compensate. This will set the code.

Fault codes P0236 and P0046 keep coming up on my freelander1 td4 2004


P0236 = Possible causes are

1. Boost pressure sensor harness is open or shorted
2. Boost pressure sensor circuit poor electrical connection
3. Faulty boost pressure sensor
4. Faulty Turbo/Super Charger
5. Engine over temperature
6. Ignition misfire exceeds the threshold
7. Faulty Knock sensor (KS)

P0046 = Turbo/Super Charger Boost Control Solenoid Circuit Range/Performance

.... based on this information I would replace the turbo boost control solenoid first.

I replaced the knock sensor, what else could be causing acceleration problems on hills?


The knock sensor code does not always mean the sensor is faulty.
The sensor picks up noise and vibration in the engine such as a spark knock would generate, and the computer slows down the spark timing to fix it. If the noise or vibration continues, the code is set.
Could be a noisy valve, or a problem with the crankshaft or other component.

It could be that your knock sensor circuit is working perfectly.You may have a knock that it is reading for long periods.
Try running it disconnected, and see if there is a clatter or knock when accelerating lightly.

You could have a vacuum leak.

More knock sensor blues


Forgive me for asking, but are you sure you replaced the knock sensors? They are underneath the intake plenum. I'm just wondering if maybe you replaced the Oxygen sensors by accident. Anyway, so that you know, this is a very common problem (the knock sensors). Gm has issued a bulletin, something to do with the rear knock sensor under the intake getting contaminated by water, and they recommend a new sensor installed with silicone around the gasket to protect it. Also, the wiring harness is particularly tasty to rodents and they get in there and eat the insulation and wires! You have to inspect the harness carefully when you have the intake off because you can't see it when it's all together. Seen this twice now.
