Code P2135 Infiniti Description

Electric Throttle Control Actuator consists of throttle control motor, throttle position sensor, etc. The throttle position sensor responds to the throttle valve movement.

The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the Engine Control Module (ECM). In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.

2. What are the symptoms of code P2135 in an Infiniti?

Common symptoms include reduced engine power, hesitation while accelerating, poor throttle response, the engine going into limp mode, and the check engine light turning on.

3. What causes the P2135 code to appear in an Infiniti?

Typical causes include a faulty throttle position sensor, wiring issues such as corrosion or damage, a dirty throttle body, or a failing electronic throttle control (ETC) system.

4. Can a dirty throttle body trigger the P2135 code?

Yes, a dirty or clogged throttle body can cause incorrect readings from the throttle position sensor, which may trigger the P2135 code.

5. How do I troubleshoot the P2135 code on my Infiniti?

First, inspect the throttle body and TPS for dirt or damage. Then, check the wiring and connectors for corrosion or loose connections. If no issues are found, test the voltage signals from the TPS.

6. Is it safe to drive with the P2135 code on my Infiniti?

Driving with this code is not recommended, as it can cause sudden loss of power or the engine entering limp mode, potentially leading to unsafe driving conditions.

7. How much does it cost to fix the P2135 code on an Infiniti?

Repair costs can vary but typically range from $100 to $500, depending on whether the issue is with the throttle body, TPS, or wiring.

8. Can the P2135 code be fixed without replacing the throttle position sensor?

In some cases, cleaning the throttle body or repairing damaged wiring can resolve the issue without replacing the sensor.

9. Does resetting the P2135 code fix the problem?

Clearing the code without addressing the underlying issue is only a temporary solution. The code will likely return if the root cause is not resolved.

10. How do I prevent the P2135 code from reoccurring in my Infiniti?
