If your Chevrolet Cruze's check engine light is on, it is essential to immediately pull over to a safe location to prevent further damage to your vehicle. Once you have safely parked, you should utilize an OBD II scan tool to retrieve the error code stored in the ECU. A P2135 code indicates an issue with the throttle position sensor switch, which is responsible for monitoring your throttle input. Any malfunction in this component can lead to reduced acceleration and an unresponsive gas pedal.
The issue with the auto trouble code p2135 is about the throttle having trouble opening and closing because of a problem with the throttle / pedal position sensor / switch a / b tension correlation.
