P0220 2015 Toyota RAV4 Code - Throttle / Pedal Position Sensor / Switch 'B' Circuit
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 P0220 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 P0220 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 P0220 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.

Frequently Asked Questions about P0220 2015 Toyota RAV4 Code
1. What does the OBDII code P0220 mean for a 2015 Toyota RAV4?
Code P0220 indicates a problem with the Throttle/Pedal Position Sensor/Switch 'B' Circuit, which monitors the position of the throttle or accelerator pedal.
2. What are the common symptoms of P0220 in a 2015 Toyota RAV4?
Symptoms may include poor acceleration, reduced engine power (limp mode), the Check Engine Light turning on, or erratic throttle response.
3. What causes the P0220 code to appear in a 2015 Toyota RAV4?
Common causes include a faulty throttle position sensor (TPS), damaged wiring or connectors, a malfunctioning accelerator pedal position sensor, or issues with the engine control module (ECM).
4. Can I drive my 2015 Toyota RAV4 with the P0220 code?
It’s not recommended to drive with this code as it can lead to unsafe driving conditions due to reduced engine power or inconsistent throttle response.
5. How do I diagnose the P0220 code in my 2015 Toyota RAV4?
Begin by inspecting the wiring and connections to the TPS and accelerator pedal sensor. If no damage is found, use a scan tool to monitor sensor readings and compare them to manufacturer specifications.
6. How can I fix the P0220 code on a 2015 Toyota RAV4?
Repairs may involve replacing the throttle position sensor, accelerator pedal position sensor, or repairing damaged wiring and connectors. In some cases, reprogramming or replacing the ECM may be necessary.
7. How much does it cost to fix the P0220 code on a 2015 Toyota RAV4?
Repair costs vary but typically range from $100 to $300 for sensor replacement. ECM repairs or replacements can be more expensive, often exceeding $500.
8. Can a dirty throttle body cause the P0220 code in a 2015 Toyota RAV4?
While unlikely, a dirty throttle body can cause related issues. Cleaning the throttle body may help if it is contributing to poor sensor readings.
9. Does the P0220 code always mean the sensor is faulty in a 2015 Toyota RAV4?
No, the issue could also stem from wiring problems, poor connections, or a malfunction in the ECM.
10. Will clearing the P0220 code fix the issue on a 2015 Toyota RAV4?
Clearing the code may reset the Check Engine Light temporarily, but the underlying issue must be resolved to prevent the code from returning.
