If the check engine light is still on there is still a problem. When you fix the problem the light will go out by its self and the fault code will stay in the ecm as a stored code until it's reset.
There are 2 knock sensor on the 5.3L engine. And they are under the intake manifold. To get to them you will have to remove the whole top of the engine- INTAKE MANIFOLD. Why do you think they need replaced???? check engine light came on for 2 sensor
If the abs and check engine lights are on there is a problem. Both computers should have codes stored in there memories. Have the codes read. You can then diagnose the cause.
Engine coolant Temperature ( ECT ) sensor does not meet minimum thermostat regulating temperature. Need to replace ECT sensor. Make sure engine is COLD before changing. The sensor is on the right head back beside the last spark plug.

There is not one sensor. All the ECM sensors are tied to the check engine light.
That is what the check engine light is for. It informs you of a failure.
If the o2 sensor is not working, the computer will put out a code which will turn on your Check Engine light. The car/truck will not pass inspection without it being fixed. Anytime the check engine light is on, the mechanic will plug into the vehicle's computer and it will tell him the fault codes and what they mean so that he can fix them. So, if the check/service engine light is off, the oxygen sensor should be fine.
If it is bad the check engine light will come on and set a code for that particular sensor.
To install the knock sensor on a 1996 BMW Z3 1.9 engine, first, ensure the engine is cool and disconnect the battery. Locate the knock sensor, which is typically positioned on the engine block near the cylinder head. Remove the old sensor by unscrewing it and disconnecting the electrical connector. Install the new sensor by connecting it and securing it in place, then reconnect the battery and start the engine to check for proper function.
Yes, an unplugged sensor can cause a check engine light.
A throttle position sensor on any car is on the side of the throttle body. You can backprobe it with a voltmeter to check its operation. If you remove it, you'll have to calibrate it with the voltmeter, adjusting it within slotted holes.
