Chrysler PT Cruiser traction and ABS lights on, possible module or electrical issue on Chrysler PT Cruiser

Some Chrysler PT Cruiser owners report experiencing issues when the traction and ABS lights illuminate, which typically indicates a problem with the Anti-lock Braking System (ABS) or traction control system. These warning lights may be triggered by a fault code stored in the ABS module, necessitating the use of a scan tool to retrieve the specific code. Common causes include problems with wheel speed sensors, wiring issues, or a faulty control module. Additionally, electrical issues such as malfunctioning sensors, switches, or throttle actuation problems can activate these lights. Some owners also note that a failing throttle position sensor can lead to overcompensation by the engine's computer, resulting in black exhaust from the tailpipe. It is recommended that affected owners have their vehicles inspected by a qualified mechanic to diagnose the issue and determine the appropriate course of action.
