How to eliminate the fault code of Familia p022 1?

Familia fault code: p022 1 detailed description is as follows:

System fault range: none at present.

Applicable model: Familia

P022 1: unreasonable signal of electronic throttle position sensor 2 is introduced into the system to continuously monitor the voltage of the throttle position sensor signal circuit. When the voltage exceeds the reasonable voltage range (the voltage difference between sensor 1 and sensor 2 exceeds a certain range), it is judged as an unreasonable signal fault.

English meaning: Not at present.

P022 1 Fault code related knowledge:

no

Cause and effect: p022 1: unreasonable signal of electronic throttle position sensor 2 0 1 detection condition 01-0/engine speed >> 1200 rpm. 0 1-02 Fault code verification method: driving cycle. 02 Possible cause 02-0 1 electronic throttle position sensor 2 is damaged. 02-02 Electronic throttle position sensor 2 is connected to other circuits. 02-03 Electronic throttle connector failure. 02-04 Electronic Throttle Position Sensor Pin Failure of Engine Control Unit 2.

Suggested solutions: 0 1 Confirm the validity of the fault code 0 1-0 1 Clear the historical fault code, detect the current fault after three consecutive driving cycles, then confirm that the MIL light and svs light of fault 0 1-02 are on, and execute Step 02 No, check the intermittent fault 02 and check whether the electronic throttle position sensor is abnormal 02-. Yes, repair or replace the wiring harness, go to step 06 No, go to step 03 Step 03 to check whether the signal wiring harness of electronic throttle position sensor 2 is abnormal. 03-0 1 Turn the ignition switch off. 03-02 Disconnect the sensor connector. 03-03 Check the wear of the sensor pin. 03-04 Whether the circuit is worn or disconnected from other circuits. Yes, repair or replace the harness, go to step 06 No, step 0404 check whether the electronic throttle connector is abnormal, 04-0 1 check whether the connector is not tightly inserted, if it is oxidized, repair or replace the connector, go to step 06 No, go to step 0505 check whether the electronic throttle position sensor 2 pin of the engine control unit is abnormal, and 05-0 1 remove the engine control. Yes, repair or replace the engine control unit, go to step 06 No, go to step 0606 Fault repair confirmation 06-0 1, and confirm that all connectors are connected. 06-02 Turn on the ignition switch. 06-03 Connect the diagnostic instrument and clear the fault code. 06-04 Conduct driving cycle test. 06-05 Read the DTC. Output the DTC again? Yes, confirm whether the corresponding detection conditions are met, and recheck according to the diagnostic procedure. No, the fault has been fixed.
