P0120 2010 TOYOTA CAMRY - Throttle Pedal Position Sensor/Switch 'A' Circuit Malfunction
- Faulty Throttle Position Sensor
- Throttle Position Sensor circuit is open or shorted
- Throttle Position Sensor poor electrical connection
Tech notesVery common problem with Toyota models. Before replacing any parts, try cleaning the throttle body and reset the light. If the codes come back, then it will necessary to replaced the throttle position sensor (TPS which is built into the throttle body).
When is the code detected?Malfunction is detected when an excessively low or high voltage from the sensor is sent to ECM.
- Engine Light ON (or Service Engine Soon Warning Light)
P0120 2010 Toyota Camry DescriptionThe 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 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.
