P0222 2015 Toyota RAV4 Code - Throttle / Pedal Position Sensor / Switch 'B' Circuit Low Input
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 P0222 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 P0222 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)

1. What does the OBDII code P0222 mean in a 2015 Toyota RAV4?
The code P0222 indicates that the Throttle/Pedal Position Sensor/Switch 'B' Circuit is registering a low input, which could suggest an issue with the sensor, wiring, or related components.
2. What are the common symptoms of P0222 in a 2015 Toyota RAV4?
Symptoms may include reduced engine performance, hesitation during acceleration, poor throttle response, the vehicle entering "limp mode," and the check engine light turning on.
3. What causes the P0222 code to appear in a 2015 Toyota RAV4?
Common causes include a faulty throttle position sensor, damaged or corroded wiring, poor electrical connections, or a malfunctioning engine control module (ECM).
4. Can I still drive my 2015 Toyota RAV4 with a P0222 code?
Driving with a P0222 code is not recommended as it may lead to poor performance, potential safety issues, and further damage to the engine or throttle system.
5. How do I diagnose the P0222 code in a 2015 Toyota RAV4?
Diagnosis typically involves using an OBDII scanner to confirm the code, inspecting the throttle position sensor and wiring for damage or corrosion, and checking the voltage and resistance of the sensor.
6. How is the P0222 code repaired in a 2015 Toyota RAV4?
Repairs may include replacing the throttle position sensor, repairing or replacing damaged wiring, cleaning corroded connections, or reprogramming or replacing the ECM if necessary.
7. How much does it cost to fix the P0222 code on a 2015 Toyota RAV4?
The repair cost varies but typically ranges from $100 to $300 for part replacement, with labor costs depending on the complexity of the repair and local rates.
8. Can a dirty throttle body cause the P0222 code in a 2015 Toyota RAV4?
While a dirty throttle body is not a direct cause of P0222, it can contribute to throttle-related issues and should be inspected and cleaned if needed.
9. Does the P0222 code always mean the throttle position sensor is bad in a 2015 Toyota RAV4?
No, the issue could also stem from wiring problems, poor electrical connections, or an ECM malfunction, so proper diagnosis is essential.
10. Will resetting the check engine light fix the P0222 code on a 2015 Toyota RAV4?
Resetting the light may clear the code temporarily, but if the underlying issue is not resolved, the code will likely return.
