It retards / slows the timing up and makes the transmission shift hard. The engine has to be running right for the transmission to work right. It would really help to know the year. There could be other problems depending on the year.
No, the knock sensor only retards the timing when it detects the engine pinging.
The Right Front ABS wheel speed sensor is also used as a rough road sensor to assist the knock sensor in dectecting weather there is a knock from engine or bump from the road in order to adjust the spark and fuel.
What might cause your 2002 Silverado 4.8 to run rough under a load could be clogged fuel injectors or a clogged fuel filter. It might also run rough under a load because of a transmission sensor issue.
YES it does. It should be close to intake.
A bad crankshaft position sensor on your Chrysler 300 will cause the engine to run very rough or not run at all. The malfunctioning sensor can cause damage to your engine, if not repaired.
Yes, sadly it can, especially in the Jeep 4.0
A bad crankshaft position sensor will cause your Kia Sorrento to run rough. The bad crankshaft position sensor can also cause your Kia to not start.
A bad throttle sensor can cause engine jerking and rough running. A test of the computer codes should show if there seems to be a problem with the sensor.
You don't mention what make or model your vehicle is, but some have a Transmission Range Sensor (TRS or DTRS) that will affect the overdrive and downshifting of the transmission. It is located on the side of the transmission and any misalignment of the sensor will cause those symptoms. However, I don't think that same sensor will make the engine run rough - but it certainly affects as mentioned above. If the SERVICE ENGINE LIGHT is ON, or has come ON lately, have it diagnozed, I am sure you will find the problem.
Not likely but possible. I would suspect a leaking vacuum hose.
Code 72- VSS signal circuit error. Check the VSS and circuit for short to ground or open circuit, a bare wire can cause an intermittent problem. Verify this first. Also check the VSS to make sure no excessive material has built up on the magnetic end, such material from the transmission wearing over a period of time cause deposit fine shavings on sensor head interfering with sensor operation. Wipe clean with paper (not cloth) towel to remove material and reinstall. A newly rebuilt transmission can deposit these quick enough as the transmission is "breaking in". If all else checks out, replace sensor.
Yes it could but, it should also illuminate the check engine light.
