HINT:

MONITOR DESCRIPTION
These DTCs indicate a problem with the park/neutral position switch assembly or the wire harness in the park/neutral position switch assembly circuit.
The park/neutral position switch assembly detects the shift lever position and sends signals to the ECM.
For safety, the park/neutral position switch assembly detects the shift lever position so that the engine can be started only when the shift lever is in P or N.
The park/neutral position switch assembly sends a signal to the ECM according to the shift lever position (P, N, R, D or S).
The ECM determines that there is a problem with the switch or related parts if it receives more than 1 position signal simultaneously and will then illuminate the MIL and store a DTC.

![2021 - 2022 MY Avalon [08/2020 - ]; UB80F (AUTOMATIC TRANSMISSION / TRANSAXLE): AUTOMATIC TRANSAXLE SYSTEM: DTC CHECK / CLEAR](/t3Portal/stylegraphics/info.gif)
- Connect the Techstream to the DLC3.
- Turn the engine switch on (IG) and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the engine switch off and wait for 2 minutes or more.
- Turn the engine switch on (IG) and turn the Techstream on.
-
Wait with the shift lever in each position (P, R, N and D) for 60 seconds or more each with the engine switch on (IG). [*1]
HINT:
[*1] : Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / Transmission / Utility / All Readiness.
- Input the DTC: P070513 or P070562.
-
Check the DTC judgment result.
