P1706

Component Description
When the gear position is "N", park/neutral position (PNP) switch is "ON". ECM detects the park/neutral position when continuity with ground exists.




CONSULT-II Reference Value in Data Monitor Mode
Specification data are reference values.




ECM Terminals and Reference value
Specification data are reference values and are measured between each terminal and 32 (ECM ground).

DTC Confirmation Procedure

CAUTION: Always drive vehicle at a safe speed.

NOTE: If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.

With CONSULT-II
1. Turn ignition switch ON.




2. Select "P/N POSI SW" in "DATA MONITOR" mode with CONSULT-II. Then check the "P/N POSI SW" signal under the following conditions.
If NG, go to "Diagnostic Procedure" below. If OK, go to following step.
3. Select "DATA MONITOR" mode with CONSULT-II.
4. Start engine and warm it up to normal operating temperature.







5. Maintain the following conditions for at least 60 consecutive seconds.
6. If 1st trip DTC is detected, go to "Diagnostic Procedure" below.

Overall Function Check
Use this procedure to check the overall function of the park/neutral position switch circuit. During this check, a 1st trip DTC might not be confirmed.

Without CONSULT-II
1. Turn ignition switch ON.







2. Check voltage between ECM terminal 22 (PNP switch signal) and body ground under the following conditions.
3. If NG, go to "Diagnostic Procedure" below.
