1 1) With the ignition switch “OFF”, disconnect the shift
position sensor connector.
2) With the ignition switch “ON”, check the voltage at the
“R” wire terminal of the shift position sensor connector.
Is the voltage approx. 4 – 5 V?
Go to step 2. • “R” wire open, “R”
wire shorted to
ground circuit or poor
connection.
• If the wiring and
connection is OK,
substitute a known-
good ECM and
recheck.
2 1) Check the shift position sensor output voltage change.
Refer to “Shift Position Sensor Inspection” in Section 1C
(Page 1C-16).
Is it in good condition?
Poor shift position
sensor connection,
intermittent trouble or a
faulty ECM may be the
cause.
• “R” wire shorted to
“P/Bl” wire, “B/W”
wire open, poor “B/
W” wire connection,
poor “P/Bl” wire
connection, “P/Bl”
wire open or poor
shift position sensor
connection.
• If the wiring and
connection is OK,
intermittent trouble or
a faulty ECM may be
the cause.
• Faulty shift position
sensor.
