P0222 2018 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 2018 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 2018 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 P0222 2018 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.

1. What does the OBDII code P0222 mean on a 2018 Toyota RAV4?
P0222 indicates that the throttle/pedal position sensor/switch 'B' circuit is reporting a voltage level that is lower than the expected range.
2. What are the common symptoms of the P0222 code in a 2018 Toyota RAV4?
Symptoms may include reduced engine power, hesitation during acceleration, an illuminated check engine light, and the vehicle entering "limp mode."
3. What causes the P0222 code to appear on a 2018 Toyota RAV4?
Common causes include a faulty throttle position sensor, damaged wiring or connectors in the sensor circuit, or a malfunctioning engine control module (ECM).
4. Can I drive my 2018 Toyota RAV4 with the P0222 code?
It is not recommended to drive with this code active, as it may cause reduced performance and potential safety issues due to limited throttle response.
5. How do I fix the P0222 code on my 2018 Toyota RAV4?
Repairs may include replacing the throttle position sensor, repairing damaged wiring or connectors, or reprogramming or replacing the ECM if necessary.
6. How much does it cost to fix the P0222 code on a 2018 Toyota RAV4?
The repair cost can range from $100 to $500 or more, depending on whether the issue is a sensor replacement, wiring repair, or ECM replacement.
7. How do I diagnose the P0222 code on my 2018 Toyota RAV4?
Diagnosis typically involves using an OBDII scanner to confirm the code, inspecting the sensor and wiring for damage, and testing the throttle position sensor's voltage output.
8. What happens if I ignore the P0222 code on my 2018 Toyota RAV4?
Ignoring the code can lead to worsening performance issues, potential stalling, and increased risk of accidents due to throttle control problems.
9. Can a dead battery cause the P0222 code in a 2018 Toyota RAV4?
A completely dead battery is unlikely to directly cause this code, but issues with the electrical system can sometimes contribute to sensor malfunctions.
10. Is the P0222 code related to other throttle position sensor codes?
Yes, P0222 may appear alongside related codes such as P0220 or P0223, indicating different issues within the throttle position sensor system.
