Cautions and notes
CAUTION: These codes may be generated in the
Primary or Secondary Powertrain Control Module
(PCM) Check that you are working on the correct
half of the engine.
NOTE: The normal operation fuel temperature range is
between -39°F (-39°C) and 253°F (123°C). A fault is
declared if the fuel rail temperature indicates outside
these limits.

Test sequence and decision path
1. Connect the WDS or scan tool and confirm that
P0180, P0182 or P0183 is present.
2. Set the datalogger to monitor both fuel rail temperatures. Run the engine and read both Fuel Rail
Temperatures.
Compare the fuel rail temperatures. If the temperature of the suspect rail is reasonable, shake /wiggle the engine harness between the fuel
temperature sensor and the PCM.
If no open circuit is detected, note the fault code
and go to the relevant step 3 or 4.
If an open circuit is identified, service the harness
as necessary. Clear the fault code and run a KOER
test to ensure that the problem is resolved.
3. P0182 - Disconnect the fuel rail temperature sensor and the primary PCM. Check for a short to
ground from primary sensor connector C2251-1.
If a short to ground is detected, service the harness as necessary. Reconnect the sensor and the
PCM. Clear the P0182 code and run a KOER test
to ensure that the problem is resolved.
4. P0183 - Disconnect the fuel rail temperature sensor and the primary PCM. Turn on the ignition
and check for a short circuit to +5 or +12 volt on
the signal line at C2251-1.
If a short circuit to +5 or +12 volts is detected,
service the harness as necessary. Clear the P0183
code and reconnect the sensor and the PCM. Run
a KOER test to ensure that the problem is
resolved.
