The P0124 fault code indicates a problem with the Throttle/Pedal Position Sensor/Switch A Circuit. This code specifically refers to an intermittent issue, meaning that the sensor may occasionally send erratic signals to the Engine Control Module (ECM). This can affect engine performance and is critical for ensuring proper throttle control.

What are the symptoms of the P0124 code?

Drivers may experience a variety of symptoms such as:

• Unresponsive or sticky throttle
• Check Engine Light illuminated
• Erratic engine speed
• Decreased power or acceleration
• Engine stalling or hesitation on acceleration

What causes the P0124 code?

Common causes of the P0124 code include:

• Faulty throttle position sensor
• Poor electrical connections or wiring issues
• Malfunctioning ECM
• Throttle body issues
• Carbon buildup in the throttle body

How to fix P0124?

To resolve the P0124 fault code, the following steps are typically recommended:

• Inspect the throttle position sensor and wiring for damage or corrosion
• Clean the throttle body to remove any carbon buildup
• Replace the throttle position sensor if faulty
• Ensure all electrical connections are secure and free of contaminants
• If necessary, reprogram or replace the ECM
