Description
The park/neutral position (pnp) switch detects the shift lever position and sends signals to the ecm.
Monitor description
These dtcs indicate a problem with the park/neutral position switch and the wire harness in the park/ neutral position switch circuit.
The park/neutral position switch detects the shift lever position and sends a signal to the ecm.
For security, the park/neutral position switch detects the shift lever position so that the engine can be started only when the shift lever is on p or n.
The park/neutral position switch sends a signal to the ecm according to the shift lever position (r, d, 3, 2 or l).
The ecm determines that there is a problem with the switch or related parts if it receives more than 1 position signal simultaneously. The ecm will illuminate the mil and store the dtc.

Inspection procedure
Hint:
Using the intelligent tester's data list allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the data list early in troubleshooting is one way to save time.
Notice:
In the table below, the values listed under "normal condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

Catalyst system efficiency below threshold (bank 1)
Monitor description
The ecm uses sensors mounted in front of and behind the three-way catalytic
converter (twc) to
monitor its efficiency.
The first sensor, the air-fuel ratio (a/f) sensor, sends pre-catalyst
information to the ecm. The second
sensor, the heated oxygen (ho2) sensor, se ...
