P0220 2016 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 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 P0220 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 P0220 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.
