P0220 2008 Toyota Camry Code - Throttle/Pedal Position Sensor/Switch 'B' Circuit

Quick Answer

The Throttle Position (TP) Sensor is mounted on the throttle body and detects the opening angle of the throttle valve. Common causes include Faulty Throttle Position Sensor, Throttle Position Sensor (TPS) harness is open or shorted, Throttle Position Sensor circuit 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 2008 Toyota Camry Description

The Throttle Position (TP) Sensor is mounted on the throttle body and detects the opening angle of the throttle valve. This sensor is a non-contact type. It uses Hall-effect elements in order to yield accurate signals even in extreme driving conditions, such as at high speeds as well as very low speeds. The TP sensor has two sensor circuits which each transmits a signal, VTA1 and VTA2. VTA1 is used to detect the throttle valve angle and VTA2 is used to detect malfunctions in VTA1. The sensor signal voltages vary between 0 V and 5 V in proportion to the throttle valve opening angle and are transmitted to the VTA terminals of the Engine Control Module (ECM).
As the valve closes, the sensor output voltage decreases and as the valve opens, the sensor output voltage increases. The 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 Diagnostic Trouble Code (DTC) will be set when an unexpected voltage from the TP is sent to ECM.
