P0850 PNP SWITCH
P0850 PNP SWITCH
Description
INFOID:0000000012197976
For CVT models, transmission range switch is turn ON when the selector lever is P or N.
For M/T models, park/neutral position (PNP) range switch is ON when the selector lever is Neutral position.
ECM detects the position because the continuity of the line (the ON) exists.

POSI SW” signal as per the following conditions.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Proceed to
.
4.
PERFORM DTC CONFIRMATION PROCEDURE
1. Select “DATA MONITOR” mode of “ENGINE” using CONSULT.
2. Start engine and warm it up to normal operating temperature.
DTC No.

process of engine starting and driving.
• For M/T models, the signal of the park/
neutral position (PNP) switch is not
changed in the process of engine starting
and driving.
• Harness or connectors
[The transmission range switch circuit is
open or shorted.(CVT models)]
[The park/neutral position (PNP) switch

3. Maintain the following conditions for at least 60 consecutive seconds.
CAUTION:
Always drive vehicle at a safe speed.
4. Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Proceed to
.
NO
>> INSPECTION END
5.
PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to
EC-427, "Component Function Check"
.
NOTE:
Use component function check the overall function of the transmission range switch circuit (CVT models) or
the park/neutral position (PNP) switch circuit (M/T models). During this check, a 1st trip DTC might not be con-
firmed.
Is the inspection result normal?
YES
