DESCRIPTION
CAUSE
ACTION
P0707
ECM
Gear position
sensor shorted to
ground, or open
circuit
Verify that gear position information
change when you change the
position of gear on vehicle.
Disconnect GBPS
Measure voltage between harness
connector GBPS-1 and GBPS-3.
(Expected value: 4.8 to 5.1 volts)
Measure resistance from
connector: ECM-D2 to GBPS-2
(Expected value: < 2 ohms)
Measure resistance from
connector: ECM-C3 to GBPS-3
(Expected value: < 2 ohms)
Replace GBPS sensor

may have been used.
Measure battery voltage with
engine stopped. (Expected
value: 11 to 13 volts)
Measure battery voltage with
engine running. (Expected
value: 13 to 14.7 volts)
Check connections
on voltage regulator.
