Check
21. Engine is running.
2. Review and record Tech 2 Failure Records data.
3. Operate the vehicle within Failure Records
conditions as noted.
4. Using a Tech 2, monitor “DTC” info for DTC P1194.
Does the Tech 2 indicate DTC P1194 failed?

Aids
3Connect a test light between B+ and the RP sensor
signal circuit at the RP sensor harness connector.
Is the RP value near the specified value.
5 VGo to Step 4Go to Step 6
41. Ignition “OFF.”
2. Disconnect the ECM and check the 5 volt reference
“J2” circuit for an open or short to ground.
3. If the 5 volt reference “J2” circuit is open or shorted
to ground, repair it as necessary.
Was the 5 volt reference “J2” circuit open or shorted to
ground?
—Verify repairGo to Step 5
5Check the 5 volt reference “J2” circuit for a poor
connection at the ECM and replace the terminal if
necessary.
Did the terminal require replacement?
—Verify repairGo to Step 6
61. Ignition “OFF.”
2. Disconnect the ECM, and check the RP signal
circuit for an open, short to ground, or short to the
sensor ground circuit.
3. If the RP sensor signal circuit is open or shorted to
ground, repair it as necessary.
Was the RP signal circuit open or shorted to ground?
—Verify repairGo to Step 7
7Check the RP sensor signal circuit for a poor
connection at the ECM and the RP sensor; replace the
terminal if necessary.
Did the terminal require replacement?
—Verify repairGo to Step 8
8Replace the ECM (Refer to the Data Programming in
Case of ECM change).
Is the action complete?
—Verify repairGo to Step 9
9Check the 2 way valve.
Was the 2 way valve darmage?
