What are the symptoms of a bad steering wheel sensor?
What are the symptoms of a bad steering wheel sensor?
Symptoms of a Bad or Failing Steering Angle Sensor
- Traction Control Light comes on. In most cases where an issue exists with the electronic stability program, an error code is triggered and stored inside the vehicle’s ECM.
- Steering wheel is loose and has “play”
- Car drives differently after a front end alignment.
What causes a steering wheel sensor to fail?
ECM: The ECM (or on some applications, a special EVO module) directly controls the EVO. Failure of the ECM (or the vehicle speed sensor), the steering wheel sensor or the EVO can cause assist problems. Repair or replace as necessary.
Can a malfunction of the Evo valve cause loss of power steering?
A properly functioning system requires proper operation of the EVO valve (see below), control module and vehicle speed sensor. A malfunction in the EVO valve can result in loss of regulated assist or even complete loss of power assist. However, this problem often is mistakenly perceived to be a defective power steering pump or steering gear.
When does the steering angle sensor wear out?
However, like any other sensor, the steering angle sensor can wear out or fail completely due to multiple factors beyond the control of most vehicle owners. When it does break or is slowly beginning to fail, it will exhibit a few common warning signs or symptoms.
Is there a torque sensor on the steering wheel?
If you have electric power steering in your car, you might have a steering torque sensor. This sensor detects how much for a driver is putting on the steering wheel when they are turning. This sensor will twist slightly as your steering wheel shaft is being turned.
What happens if the steering wheel sensor is bad?
Failure of any of these components will affect the steering assist. Sensor Test: If the steering wheel position sensor is bad, the vehicle ECM, in most cases, will detect this and set a Diagnostic Trouble Code (DTC). If no code is set, temporarily disconnect the senor then see if erratic assist stops or assist returns.
When to reset a bad steering angle sensor?
This applies if you have an electric power steering pump, which most modern cars have. If your car is acting a bit weird or driving strangely even after a wheel alignment, it might be due to a failing steering angle sensor. It is important and necessary to reset the steering angle sensor after an alignment.
How does the GM EVO steering system work?
controlled fluid flow to the steering gear. At slow speeds the EVO solenoid is fully open making the steering easier. At high speeds the EVO closes, restricting the flow, which makes the steering firmer. Due to inconsistent steering feel, GM introduced a kit (19168825) to remove the EVO component from the system.
What happens when the power steering switch goes bad?
As soon as the power steering pressure switch starts to go bad, the computer will not be able to keep up with the demand of the power steering system and make proper adjustments. One symptom of this is the engine will slow down when you turn a corner, or while you are driving at low speeds.
