Code B1988 Description
The B1988 diagnostic trouble code (DTC) refers to a malfunction in the pedal position forward switch circuit, specifically indicating a short to the battery. This code typically affects vehicles with electronic throttle control systems, where the pedal position is crucial for determining the appropriate throttle response. The pedal position forward switch is responsible for signaling to the vehicle's engine control module (ECM) the driver's intention to accelerate. A short to the battery in this circuit can disrupt this communication, leading to potential performance issues and safety concerns.
Common Causes of B1988
- Damaged wiring or connectors in the pedal position forward switch circuit
- Faulty pedal position sensor or switch
- Malfunctioning engine control module (ECM)
- Short circuit due to water intrusion or corrosion
- Electrical issues in the throttle control system
Symptoms of B1988
- Erratic acceleration or throttle response
- Engine hesitation or stalling
- Reduced fuel efficiency
- Limp mode activation
- Illuminated check engine light
How to Fix B1988
- Begin by diagnosing the specific cause of the short circuit using a scan tool to retrieve the DTC and inspect the pedal position forward switch circuit.
- Check the wiring and connectors for any signs of damage, corrosion, or loose connections. Repair or replace as necessary.
- Test the pedal position sensor and switch for proper functionality. Replace if faulty.
- Inspect the ECM for any signs of malfunction and reprogram or replace if needed.
- Clear the DTC and perform a test drive to ensure the issue has been resolved.
Cost to Fix B1988
The typical repair costs for addressing a pedal position forward switch circuit short to battery issue can range from $200 to $500, including parts and labor.
