Code P2135 2008 Nissan Pathfinder Description
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.
What are the Possible Causes of the DTC P2135 2008 Nissan Pathfinder?
- Faulty Electric Throttle Control Actuator (TP sensor 1 and 2)
- Electric Throttle Control Actuator harness is open or shorted
- Electric Throttle Control Actuator circuit poor connection
- Faulty Accelerator Pedal Position Sensor

Frequently Asked Questions about P2135 2008 Nissan Pathfinder Code
1. What does the OBDII code P2135 mean on a 2008 Nissan Pathfinder?
The P2135 code indicates that there is a problem with the throttle position sensor's circuit regarding its range or performance. This sensor measures the position of the throttle in the engine, sending signals to the engine control unit.
2. What are the common symptoms of code P2135 in a 2008 Nissan Pathfinder?
Symptoms include erratic engine behavior such as sudden stalling, rough idling, a lack of power, and the engine failing to respond to the acceleration pedal. The check engine light will also illuminate.
3. What causes the P2135 code to appear on a 2008 Nissan Pathfinder?
Common causes include a faulty throttle position sensor, poor electrical connections at the throttle position sensor, or a damaged throttle body. Issues with the wiring harness related to the sensor circuit can also trigger this code.
4. Can I drive my 2008 Nissan Pathfinder with the P2135 code?
While you might be able to drive, it is not advisable. Driving with this code can lead to unpredictable vehicle behavior and potentially dangerous situations. It is best to address the issue promptly.
5. How is the P2135 code diagnosed in a 2008 Nissan Pathfinder?
Diagnosis involves using an OBD-II scanner to confirm the code, visually inspecting the throttle body, throttle position sensor, and associated wiring. A technician might also test the sensor's function with a multimeter to check for proper voltage and resistance levels.
6. What repairs can fix the P2135 code in a 2008 Nissan Pathfinder?
Repairs might include replacing the throttle position sensor, repairing or replacing damaged wiring, or cleaning or replacing the throttle body if it is malfunctioning.
7. What should I check first when troubleshooting the P2135 code in a 2008 Nissan Pathfinder?
Start by checking the throttle position sensor and its connections for any signs of damage or loose connections. Also, inspect the wiring harness for any visible signs of wear or damage.
8. Is it expensive to fix the P2135 code in a 2008 Nissan Pathfinder?
The cost can vary widely depending on the specific repair needed. Replacing a throttle position sensor can be relatively affordable, but more extensive electrical repairs or replacing the throttle body can be more costly.
9. Could a P2135 code be triggered by anything other than the throttle position sensor itself in a 2008 Nissan Pathfinder?
Yes, although the throttle position sensor is a common cause, issues like a malfunctioning powertrain control module (PCM) or problems with other sensors like the accelerator pedal position sensor can also trigger this code.
10. How often does the throttle position sensor need to be replaced in a 2008 Nissan Pathfinder?
The throttle position sensor does not have a regular replacement schedule and should only need to be replaced if it fails or contributes to an issue like the P2135 code. Regular inspections during routine maintenance can help catch potential problems early.
