Possible oil Leak at Knock Sensor


if I'm not mistaken, the knock sensor is mounted on the transmission bell close to the motor and detects the flywheel position. It is possible that the valve cover gaskets might be leaking from the bottom side and dripping onto the knock sensor, but it is also possible that the leak might be from the rear main seal of the motor. If that is the case, you will have to drop the ****** to replace the seal. If the knock sensor was bad your vehicle would not start at all, just crank. Try to wipe all the old oil with rags and look very closely where it gets oily again

On my 1991 chevy blazer s10 I get error code 43. What is it and how do I fix it


Hi, the indication is that your computer is not receiving a good signal from the knock sensor. Recommend you check the connector on the sensor and the wire. Also make sure the sensor isn't loose in the block. If those look good, you may want to just replace the sensor. A new one is $30 at autozone. Without the knock sensor signal, the computer will default the ignition timing toward a less fuel efficient value. The sensor looks like the picture below and is mounted in the engine block. You may have 2 knock sensors--one on each side of the engine. Sorry, but I could not find a good picture of the location. I will keep looking for one, though.

How do I replace a knock sensor for a 1992 toyota camry v6 le


First, I would like to mention that most knock sensor codes are not caused by the knock sensors, but a mechanical problem with the engine. The knock sensors cannot differentiate between noises caused by mechanical problems like a bad pulley bearing, bad motor mount, noisy alternator bearings, etc. and spark knock. knock sensor codes are set when the computer has retarded the timing as far as possible to compensate for ignition ping (Spark Knock) and the noise still exists.

With that said, here are the instructions.

Remove the Intake Chamber assembly.
Disconnect Injector connectors.
Disconnect the heater hose from the Intake Manifold.
Remove the 9 bolts. 2 nuts, 2 plate washers and Intake Manifold assembly.
Remove right hand engine mounting stay and water outlet.
Disconnect the following hoses and connectors:
Radiator inlet hose.
Engine coolant reservoir hose.
Engine Coolant Temperature Sensor connector.
Engine Coolant Temperature Switch connector.
Ground strap connector.

Remove the 3 bolts and right hand mounting stay.
Remove the wire band.
Disconnect the water bypass hose from the inlet housing.
Remove the 2 bolts, 2 nuts, 2 plate washers and water outlet.
Remove the 2 gaskets.
Disconnect the Knock Sensor connectors.
Remove the Knock Sensors.

Either your valves are knocking. Your IAC (Idle Air Control valve), or your knock sensor. The only thing is that if your knock sensor is bad it would throw a code. Your caddy could be the problem but again it would throw a code
