Code P2135 2014 Chevrolet Silverado Description
When the P2135 diagnostic trouble code is triggered in a 2014 Chevrolet Silverado, it indicates that there is a discrepancy between the readings of throttle position sensors 1 and 2, which are responsible for monitoring the position of the throttle pedal. This inconsistency can cause the vehicle's engine control module (ECM) to detect a fault in the throttle position control system. Essentially, the ECM receives signals from both sensors and expects them to correlate with each other. If the readings from the sensors do not match up, the ECM will set the P2135 code.
Common Causes of P2135 2014 Chevrolet Silverado
- Faulty throttle position sensors
- Wiring or connector issues
- Corrosion or dirt on sensor contacts
- ECM software or hardware issues
- Mechanical issues with the throttle body
Symptoms of P2135 2014 Chevrolet Silverado
- Reduced engine power
- Unresponsive throttle
- Rough idling or stalling
- Check Engine Light illuminated
- Reduced fuel efficiency
How to Fix P2135 2014 Chevrolet Silverado
- Inspect the throttle position sensors and wiring for any signs of damage or corrosion.
- Clean the sensor contacts and connectors to ensure proper electrical connections.
- Test the throttle position sensors using a multimeter to check for accurate readings.
- Replace any faulty sensors or damaged wiring as needed.
- Clear the diagnostic trouble codes and reset the ECM to see if the issue persists.
Cost to Fix P2135 2014 Chevrolet Silverado
The typical repair costs for addressing a P2135 code in a 2014 Chevrolet Silverado can vary depending on the specific cause of the issue.

Frequently Asked Questions about P2135 2014 Chevrolet Silverado Code
1. What does OBDII code P2135 mean on a 2014 Chevrolet Silverado?
P2135 indicates a correlation issue between the readings of Throttle Position Sensor (TPS) 1 and TPS 2, meaning the sensors are not providing matching data to the engine control module (ECM).
2. What are the common symptoms of code P2135 in a 2014 Chevrolet Silverado?
Symptoms may include reduced engine power mode (limp mode), poor throttle response, hesitation during acceleration, the check engine light turning on, and sometimes stalling.
3. What are the main causes of P2135 in a 2014 Chevy Silverado?
Common causes include a faulty throttle body, damaged throttle position sensors, wiring or connector issues, or even a failing ECM.
4. Can a dirty throttle body trigger code P2135?
Yes, a dirty or carbon-clogged throttle body can cause the sensors to send inaccurate readings, leading to the P2135 code.
5. Is it safe to drive with code P2135 on a 2014 Chevrolet Silverado?
Driving is not recommended as the vehicle may enter reduced engine power mode, causing safety risks like sudden loss of power.
6. How can I diagnose the cause of code P2135?
Start by inspecting the throttle body and its wiring for damage, cleaning the throttle body if needed, and using a scan tool to compare data from TPS 1 and TPS 2.
7. How do I fix code P2135 on a 2014 Chevrolet Silverado?
Fixes may involve cleaning or replacing the throttle body, repairing faulty wiring or connectors, or replacing the throttle position sensors if they are defective.
8. Do I need to replace the entire throttle body for code P2135?
Not always. If the issue is with the sensors or wiring, replacing the throttle body may not be necessary. However, if the throttle body itself is malfunctioning, replacement might be required.
9. Can a software update fix the P2135 code on a 2014 Chevrolet Silverado?
In some cases, a software update from the dealership can resolve the issue, especially if the ECM is misinterpreting the sensor data.
10. How much does it cost to repair code P2135 on a 2014 Chevrolet Silverado?
Repair costs vary but typically range from $200 to $600, depending on whether you need to clean the throttle body, repair wiring, or replace components like the throttle body or sensors.
