Code P2135 2008 Honda Accord Description
The P2135 code on a 2008 Honda Accord indicates a Throttle Position Sensor 1/2 Incorrect Voltage Correlation. This means that there is a discrepancy between the voltage readings of the two throttle position sensors in the vehicle. The throttle position sensor (TPS) is a crucial component that monitors the position of the throttle valve and sends this information to the engine control module (ECM). The ECM uses this data to determine the appropriate air-fuel mixture for combustion in the engine.
Common Causes of P2135 2008 Honda Accord
- Faulty throttle position sensor
- Wiring issues or shorts
- Corrosion or poor connections in the sensor circuit
- ECM malfunction
- Environmental factors such as moisture or debris affecting sensor performance
Symptoms of P2135 2008 Honda Accord
- Erratic engine behavior
- Poor acceleration
- Stalling
- Limp mode activation
- Decreased fuel efficiency
How to Fix P2135 2008 Honda Accord
- Diagnose the specific cause of the P2135 code using a diagnostic scanner to pinpoint the issue accurately.
- Inspect the throttle position sensors and wiring for any visible damage or corrosion.
- Test the throttle position sensors for proper voltage output and resistance.
- Replace any faulty throttle position sensors or repair wiring issues as needed.
- Clear the code from the ECM and perform a test drive to ensure the issue is resolved.
Cost to Fix P2135 2008 Honda Accord
The typical repair costs for addressing a P2135 code on a 2008 Honda Accord can range from $150 to $400, including parts and labor.

Frequently Asked Questions about P2135 2008 Honda Accord Code
1. What does OBDII code P2135 mean on a 2008 Honda Accord?
P2135 indicates a voltage correlation issue between Throttle Position Sensor 1 and Sensor 2, which monitor the throttle plate's position in the electronic throttle control system.
2. What are the symptoms of P2135 on a 2008 Honda Accord?
Common symptoms include reduced engine power, hesitation during acceleration, the throttle becoming unresponsive, and the Check Engine Light turning on.
3. What causes the P2135 code on a Honda Accord?
The main causes are faulty throttle position sensors, damaged wiring or connectors, a malfunctioning throttle body, or software issues in the engine control module (ECM).
4. Can I drive my 2008 Honda Accord with the P2135 code?
It’s not recommended to drive with this code because it can lead to reduced power mode or unsafe driving conditions due to throttle control issues.
5. How do I diagnose the P2135 code on a Honda Accord?
Start by inspecting the throttle body, wiring, and connectors for damage or corrosion. Use a scan tool to monitor the voltage readings of both throttle position sensors and check for inconsistencies.
6. How do I fix the P2135 code on a 2008 Honda Accord?
Repairs may include cleaning or replacing the throttle body, replacing the throttle position sensors, repairing damaged wiring, or reprogramming the ECM.
7. How much does it cost to repair a P2135 code on a Honda Accord?
The cost varies, but throttle body replacement typically ranges from $200 to $600, depending on parts and labor.
8. Can cleaning the throttle body fix the P2135 code?
Yes, carbon buildup on the throttle body can cause issues, and cleaning it may resolve the code if the sensors and wiring are otherwise functional.
9. Does the P2135 code always mean the throttle body needs replacement?
No, it could also be caused by wiring issues or sensor faults. Proper diagnosis is necessary to determine the exact cause.
10. Will resetting the Check Engine Light fix the P2135 code on my 2008 Honda Accord?
Resetting the light without addressing the underlying issue will not fix the problem, and the code is likely to return.
