Yes, a faulty idle control valve can trigger the service engine light. When the idle control valve malfunctions, it can lead to erratic engine idling or stalling, causing the engine control unit (ECU) to detect an issue. This triggers the check engine light as a warning to the driver that there's a problem that needs attention. It's advisable to have the vehicle diagnosed to identify the exact cause of the warning light.

Why would your 2006 Mitsubishi endeavor tcl light and service engine soon light come on and the car shakes this just started?

The TCL (Traction Control Light) and Service Engine Soon light coming on in your 2006 Mitsubishi Endeavor, coupled with the car shaking, could indicate several issues. Common causes include problems with the engine such as misfires, faulty spark plugs, or issues with the fuel system. Additionally, a malfunctioning traction control system or a faulty wheel speed sensor could trigger the TCL light. It's advisable to have the vehicle diagnosed with an OBD-II scanner to pinpoint the exact issue and prevent further damage.


What happens with a faulty coolant temperature sensor?

A faulty coolant temperature sensor can lead to inaccurate readings of the engine's temperature, which may cause the engine control unit (ECU) to mismanage fuel injection and ignition timing. This can result in poor engine performance, increased emissions, and, in some cases, overheating if the sensor fails to signal that the engine is running too hot. Additionally, it can trigger warning lights on the dashboard and may lead to further engine damage if not addressed promptly.


Could faulty spark plugs cause engine light to stay on?

Yes. Your Check Engine light or Service Engine Soon light.


Will a faulty coolant sensor make your car overheat?

Yes, a faulty coolant sensor can cause your car to overheat. The sensor provides critical information about the coolant temperature to the engine control unit, which regulates the cooling system. If the sensor fails, it may not signal the need for additional cooling, leading to overheating. Additionally, it can trigger the check engine light, indicating potential issues within the cooling system.


Does a faulty coolant sensor effect the engine performance?

Yes, a faulty coolant sensor can negatively affect engine performance. It may provide inaccurate temperature readings to the engine control unit (ECU), leading to improper fuel mixture adjustments and potentially causing issues like overheating or poor fuel efficiency. Additionally, it can trigger warning lights and affect other systems reliant on accurate coolant temperature data. Overall, this can lead to decreased engine efficiency and performance.

What causes the engine to hesitate or die when throttle is applied in gear on a 1996 Saturn dohc only at operating temp no service codes all censers check out?

I'm thinking either faulty fuel pump or faulty coil pack. I'm leaning more towards the coil pack. These are notorious for breaking down when the engine get's hot. However, they should kick a service engine light which you say they are not. Which may lead to a faulty fuel pump.

Why doesnt your 1996 Saturn pick up speed as you merge onto the highway It hesitates even if you floor it It feels like its going to backfire or something but it doesnt actually backfire?

there are alot of components that can cause this action. my first question to you would be, Is the check engine light on? Does it ever come on while accelerating? for diagnostic purposes only, if there is no check engine light, try and get the vehicle scanned anyways. sometimes there are pending codes that will not trigger the check engine light to come on. if you get a code you can diagnose further, and more accurately. as for the components that could cause hesitation during accelleration, i have included a list. Faulty/Failing Ignition control module Faulty Ignition coil(s) Faulty ignition wire(s) Faulty Spark plug(s) Faulty injector(s) Faulty Air Intake Tempature Sensor Failing fuel pressure regulator Failing Idle Air Control valve Failing Throttle Position Sensor Failing Oxygen Sensor(s)
