P0223 2017 Toyota RAV4 Code - Throttle / Pedal Position Sensor / Switch 'B' Circuit High 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 P0223 2017 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 P0223 2017 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 P0223 2017 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.

Frequently Asked Questions about P0223 2017 Toyota RAV4 Code
What does the OBDII code P0223 mean on a 2017 Toyota RAV4?
The P0223 code indicates a high input signal from the throttle or pedal position sensor 'B' circuit, meaning the sensor is sending voltage outside the expected range.
What are common symptoms of code P0223 in a 2017 Toyota RAV4?
Symptoms can include reduced engine performance, difficulty accelerating, poor fuel efficiency, the check engine light being on, and potential limp mode activation.
What causes the P0223 code in a 2017 Toyota RAV4?
Common causes include a malfunctioning throttle position sensor, damaged wiring or connectors in the sensor circuit, or issues with the engine control module (ECM).
Can I drive my 2017 Toyota RAV4 with the P0223 code?
Driving with this code is not recommended as it can affect engine performance and safety; the vehicle may enter limp mode or lose acceleration control.
How do I diagnose the P0223 code on a 2017 Toyota RAV4?
Diagnosis typically involves using an OBDII scanner, visually inspecting sensor wiring and connectors, and testing the throttle position sensor for proper voltage readings.
How do I fix the P0223 code on a 2017 Toyota RAV4?
Repair options may include replacing the throttle position sensor, repairing damaged wiring or connectors, or resetting the ECM after resolving the issue.
What tools are needed to fix the P0223 code in a 2017 Toyota RAV4?
You’ll typically need an OBDII scanner, a multimeter to test voltage and continuity, and possibly basic hand tools for sensor replacement.
How much does it cost to repair the P0223 code on a 2017 Toyota RAV4?
Repair costs can vary, but throttle position sensor replacement generally ranges from $100 to $300, including parts and labor.
Can a dirty throttle body cause the P0223 code on a 2017 Toyota RAV4?
While less common, a dirty or sticking throttle body can interfere with sensor readings and may contribute to this code.
Will clearing the P0223 code fix the issue on a 2017 Toyota RAV4?
Clearing the code will reset the check engine light, but unless the underlying issue is resolved, the code is likely to return.
