13.Reconnect sensor harness to
engine position sensor. Check
for open circuit:
If engine harness requires
replacement, notify SRA.
a. Measure resistance from
pin 49 to pin 50 of engine
harness connector. Resis-
tance should be 1000-2000
ohms.
b. Measure resistance from
pin 47 to pin 48 of engine
harness connector. Resis-
tance should be 1000-2000
ohms.

CORRECTIVE ACTION
Error Code 1121 - Engine Position Sensor
Circuit Failure
1. Ensure that ignition switch is
in OFF position. Disconnect
engine harness from engine
position sensor (WP 0093
00).
2. Inspect engine harness and
engine
position
sensor
connectors
for
dirty,
corroded, bent, broken, and
pushed back or extended pins.
Clean and repair connector(s) as
required (WP 0111 00).
3. Check engine harness and
engine position sensor for dirt
or
moisture
in
or
on
connectors and for missing or
damaged connector seals.
Remove dirt and moisture from
connector. Replace missing or
damaged connector seals (WP
0111 00).
4. Check for short circuit to
ground:
If resistance is not as specified,
replace engine position sensor
(WP 0093 00).
a. Measure resistance from
engine
position
sensor
connector pin A to engine
block ground. Resistance
should be greater than 100k
ohms.
