P2135 2016 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 2016 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 2016 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 2016 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?

Frequently Asked Questions about P2135 2016 Toyota RAV4 Code
1. What does OBDII code P2135 mean on a 2016 Toyota RAV4?
Code P2135 indicates a voltage correlation issue between the throttle position sensors (TPS) A and B, meaning the two sensors are not reading in sync as expected.
2. What are the common symptoms of code P2135 on a 2016 Toyota RAV4?
Symptoms may include reduced engine power, the Check Engine Light turning on, poor throttle response, or the vehicle entering "limp mode" to prevent further damage.
3. What causes code P2135 in a 2016 Toyota RAV4?
Common causes include a faulty throttle position sensor, damaged wiring or connectors, throttle body issues, or contamination affecting the sensors.
4. Can a dirty throttle body trigger code P2135 on a 2016 Toyota RAV4?
Yes, a dirty or carbon-clogged throttle body can cause incorrect sensor readings and trigger this code.
5. How do I fix code P2135 on my 2016 Toyota RAV4?
Repairs may include cleaning the throttle body, inspecting and repairing wiring and connectors, or replacing the throttle position sensor or throttle body assembly if needed.
6. Is it safe to drive my 2016 Toyota RAV4 with code P2135?
Driving with this code is not recommended, as it can result in reduced power or sudden loss of throttle response, posing a safety risk.
7. How do I diagnose code P2135 on a 2016 Toyota RAV4?
Diagnosis involves using a scan tool to check live data from the throttle position sensors, inspecting wiring and connectors for damage, and testing the throttle body for proper operation.
8. Can a faulty accelerator pedal position sensor cause code P2135 in a 2016 Toyota RAV4?
While less common, a faulty accelerator pedal position sensor can potentially cause this code, as it's part of the vehicle's electronic throttle control system.
9. How much does it cost to repair code P2135 on a 2016 Toyota RAV4?
Repair costs vary but can range from $100 for cleaning or minor wiring repairs to $500 or more if the throttle body assembly needs replacement.
10. Will clearing the code P2135 with a scan tool fix the issue permanently?
No, clearing the code without addressing the underlying problem will only temporarily turn off the Check Engine Light, and the issue is likely to reoccur.
