P1892 Chevrolet Code - Throttle Position Sensor PWM Signal High
Quick Answer
The P1892 Chevrolet code indicates that the throttle position sensor (TPS) is sending a high PWM (Pulse Width Modulation) signal to the engine control module (ECM). Common causes include Faulty throttle position sensor, Wiring or connector issues in the TPS circuit, ECM software issues. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1892 Chevrolet Description
The P1892 Chevrolet code indicates that the throttle position sensor (TPS) is sending a high PWM (Pulse Width Modulation) signal to the engine control module (ECM). The TPS is responsible for monitoring the position of the throttle valve and sending this information to the ECM to adjust fuel delivery and ignition timing. When the PWM signal is too high, it can lead to incorrect fuel and air mixture, affecting the engine's performance and fuel efficiency.
Common Causes of P1892 Chevrolet
- Faulty throttle position sensor
