P2135 2015 Toyota RAV4 Code - Throttle / Pedal Position Sensor / Switch 'A' / 'B' Voltage Correlation
Quick Answer
The throttle position sensor is mounted on the throttle with motor body assembly and detects the opening angle of the throttle valve. Common causes include Faulty Throttle Position Sensor (built into Throttle Body Assembly), Throttle Position Sensor circuit is open or shorted, Throttle Position Sensor poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2135 2015 Toyota RAV4 Description
As the valve closes, the sensor output voltage decreases and as the valve opens, the sensor output voltage increases. The Engine Control Module (ECM) calculates the throttle valve opening angle according to these signals and controls the throttle actuator in response to driver inputs. These signals are also used in calculations such as air-fuel ratio correction, power increase correction, and fuel-cut control.
The ECM uses the throttle position sensor to monitor the throttle valve opening angle. There are several checks that the ECM performs to confirm the proper operation of the throttle position sensor.
This sensor transmits two signals, if the output voltage difference between the two signals deviates from the normal operating range, the ECM interprets this as a malfunction in the throttle position sensor. The ECM illuminates the MIL and stores the Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P2135 2015 Toyota RAV4?
- Faulty Throttle Position Sensor (built into Throttle Body Assembly)
- Throttle Position Sensor circuit is open or shorted
- Throttle Position Sensor poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P2135 2015 Toyota RAV4?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0

Frequently Asked Questions about P2135 2015 Toyota RAV4 Code
1. What does OBDII code P2135 mean on a 2015 Toyota RAV4?
P2135 indicates a voltage correlation issue between the throttle position sensor (TPS) A and B, which monitor the throttle body and pedal position sensor.
2. What are the symptoms of code P2135 in a 2015 Toyota RAV4?
Common symptoms include reduced engine power (limp mode), poor acceleration, stalling, and the check engine light being illuminated.
3. What causes the P2135 code to appear in a Toyota RAV4?
Common causes include a faulty throttle position sensor, damaged wiring or connectors, a malfunctioning pedal position sensor, or a problem with the throttle body.
4. Can I drive my 2015 Toyota RAV4 with a P2135 code?
It is not recommended to drive with a P2135 code because the vehicle may go into limp mode or stall unexpectedly, posing safety risks.
5. How do I fix the P2135 code on my Toyota RAV4?
Repairs may involve cleaning or replacing the throttle body, inspecting and repairing damaged wiring, or replacing the throttle or pedal position sensor.
6. Does the P2135 code require throttle body replacement?
Not always. It may only require cleaning or recalibration of the throttle body if the issue is caused by carbon buildup or minor misalignment.
7. How much does it cost to repair a P2135 code on a 2015 Toyota RAV4?
Repair costs can vary but typically range from $150 to $600 depending on whether the throttle body, sensors, or wiring need replacement.
8. Can a dirty throttle body cause the P2135 code?
Yes, carbon buildup in the throttle body can lead to sensor misreadings and trigger the P2135 code.
9. Do I need to reprogram the ECU after fixing the P2135 code?
In some cases, the ECU may need to be reset or reprogrammed to clear the code and recalibrate the throttle system.
10. Can a loose wiring connection cause the P2135 code?
Yes, damaged or loose wiring and connectors between the throttle position sensor and ECU can cause voltage correlation issues and trigger the code.
