When slowing down sometimes my traction control light comes on and nothing happens when I press the accelerator pedal

Hi,

Have you had the computer scanned to see if there are diagnostic trouble codes stored? Also, does this only happen when coming to a stop or do you lose power while driving?

Most parts stores will scan the computer to see if there are codes. If you haven't done that, most do it for free. If you can, have that done and let me know the codes that are found. Also, as far as the traction control light turning on, it is most likely associated with a wheel speed sensor, but that shouldn't cause the engine to stall or not respond.

I will tell you that there is a throttle position sensor on the gas pedal. That can be causing issues with the driveability concerns, but not the ABS. Is the traction control light the only one that turns on?

Let me know.

What shift solenoid was indicated on the scan? Do you have the code?

Hi, Tracy. Honestly, there are a few of them, and any one will cause shifting problems. The reason I ask is because it could be related to the traction control issue. Since the car shuts off when you stop, I'm questioning if it has something to do with the torque converter clutch solenoid. If you look at the attached pic, I highlighted the shift solenoids as well as two others that can cause issues. I hope you understand, that's why I needed the code.

Here is a list of the solenoids indicated in the picture.

Electronic Components

13 - TFP Manual Valve Position Switch Assembly
46 - Input Speed Sensor
62 - Output Speed Sensor
305 - 1-2 and 2-3 Shift Solenoid Valves
305 - 1-2 and 2-3 Shift Solenoid Valves
312 - Pressure Control Solenoid
335 - TCC Control PWM Solenoid

Since it stalls when coming to a stop, I suspect the torque converter clutch (TCC) control solenoid is failing. Please understand, that is an educated guess at this point. If it doesn't release, the converter will continue to stay locked and when you stop, it would fill similar to not pushing in the clutch on a manual transmission.

I need the code to confirm. And yes, it the TCC is locked on, I believe you will lose traction control.

That kind of issue sounds more like a crankshaft position sensor, vacuum leak, or fuel pressure issue. Let me know if you find the codes. I feel confident it will point us in the right direction.

Let me know if I can help.
