OPERATION
- Refer to Code No. P0122: Throttle Position Sensor (main)
Circuit Low Input
.
- Refer to Code No. P0222: Throttle Position Sensor (sub) Circuit Low Input .
FUNCTION
- Engine-A/T-ECU checks the throttle position sensor output signal characteristics for abnormal conditions.
TROUBLE JUDGMENT
Check Conditions
- Ignition switch is in "ON" position.
- Throttle position sensor (main) output voltage is 0.35 - 2.5 V. <Vehicles for Hong kong>
- Throttle position sensor (main) output voltage is 0.2 - 4.8 V. <Vehicles except for Hong kong>
- Throttle position sensor (sub) output voltage is 2.25 - 4.8 V. <Vehicles for Hong kong>
- Throttle position sensor (sub) output voltage is 0.2 - 4.8 V. <Vehicles except for Hong kong>
Judgment Criteria
- Using the formula given below, the voltage of 0.3 V or higher is obtained for 0.5
second: V*-
V**-
2 V
V*: throttle position sensor (main) output voltage
V**: throttle position sensor (sub) output voltage. <Vehicles for Hong kong>
- Voltage obtained with the formula given below is 0.3 V or higher for 0.5 second: throttle position sensor (main) output voltage -[throttle position sensor (sub) output voltage - 2 V]. <Vehicles except for Hong kong>
- Throttle position sensor (main) output voltage is 2.5 V or higher for 0.5 second. <Vehicles except for Hong kong>
- Throttle position sensor (sub) output voltage is 4.2 V or less for 0.5 second. <Vehicles except for Hong kong>
- Throttle position sensor (main) output voltage 2.5 V or higher for 0.5 second. <Vehicles except for Hong kong>
PROBABLE CAUSE
- Failed throttle position sensor
- Open/short circuit in throttle position sensor circuit or loose connector contact
