Can a bad throttle position sensor cause idle surging?

Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. 3) Check Engine Light

What causes cyclic vibration on a FWD drive?

On some FWD driveshafts, a “vibration damper” weight is used to control torsional vibrations. If the weight has been removed or lost, it may cause cyclic vibrations to occur at certain speeds. Worn U-joints on RWD driveshafts can cause vibrations at any speed as can an incorrectly installed U-joint.

What causes the Check Engine light to turn off at idle?

At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges. The check engine light will randomly turn on and off even if the car is running smoothly without any jerks and stalling.

Why does my DSC light come on when brake fluid is low?

When the brake fluid is low you will have the ABS and DSC light coming on. In some instances, you could have old brake fluid that causes it to become acidic. If the brake fluid is low top it with a recommended brand. Each wheel has sensors that collect and pass vital information about the car’s wheel speed to the DSC.

What does DSC stand for in a car?

DSC stands for Dynamic Stability Control and is a system that helps a driver maneuver the car during over/understeering. The DSC analysis the speed of individual car wheels and whenever it senses that the driver is losing control of the car, it will activate ABS for that wheel and even cut engine power.

Can a bad speed sensor stop a car from starting?

A bad crankshaft or camshaft position sensor may prevent the car from starting. Some vehicles have redundant sensors that allow the vehicle to start and run even if one speed sensor is bad. In these cases, you are likely to see a check engine light with a code that should give you a clue which speed sensor is faulty.

Can a tire pressure sensor trigger a warning light?

If you have an indirect TPMS system then you’re unlikely to see a light on the dash due to this, assuming of course that the pressure changes in all four tires equally. In the case of a vehicle with a direct TPMS system though, which measures the actual pressure inside your tire, such changes in temperature can very easily trigger a warning light.

When does the tire pressure sensor go off?

They are programmed slightly differently in every vehicle, but as a general rule they detect when a tire’s pressure has dropped 25% or more below the recommended pressure. This is considered a dangerously low pressure level, and will trigger a warning light or message on the dash.

What happens when the transmission speed sensor is lost?

The vehicle speed sensor (VSS) is also commonly referred to as a transmission speed sensor or output shaft speed sensor. It is a small device—typically mounted somewhere on the transmission—that determines how fast your vehicle is going by measuring the rotation of a toothed wheel on a shaft inside the transmission.

Can a bad speed sensor affect shift timing?

Harsh or improper shifting. Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal. It’s also common that a problem with these sensors can impact the shift timing,…

Is the wheel speed sensor the same as the transmission?

The wheel speed sensor is different than the speed sensor attached inside the vehicle’s transmission. Its job is to record the actual wheel speed and report this data to the vehicle ECU which controls all electronic functions on the car, truck, or SUV.

What happens when a wheel speed sensor fails?

As the hub begins to spin the voltage will rise and then decrease as it stops. Slowly spin the hub or axle which will produce the voltage, if no readings can be found the sensor has failed and replacement is required. This is a typical reading from a wheel sensor.
