Are the transmission range switch signals OK?
YES
Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between the transmission range switch and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.?
NO
The failure is duplicated. Go to step 2.
