The PCM monitors the fuel pump (FP) circuit output from the PCM. The test fails if: With the FP output commanded ON (grounded), excessive current draw is detected on the FP circuit; or with the FP output commanded OFF, voltage is not detected on the FP circuit (the PCM expects to detect VPWR voltage coming through the fuel pump relay coil to the FP circuit). Open or shorted fuel pump (FP) circuit
Open VPWR circuit to fuel pump relay
Damaged fuel pump relay
Damaged PCM
When the FPF PID reads YES, a fault is currently present.

For 5.4L SC Lightning, damaged IFS switch, IFS switch relay, or concern with related circuits.
During KOEO self-test, the PCM will command the fuel pump ON so this test can be performed.

P0232 Ч Fuel Pump Secondary Circuit High NOTE: For natural gas applications, the following description applies to the fuel shutoff valve monitor (FSVM) and the fuel shutoff valve power (FSV PWR) circuits.
The PCM monitors the fuel pump monitor (FPM) circuit. This test fails when the PCM detects voltage on the FPM circuit while the fuel pump is commanded OFF. The FPM circuit is wired to a pull-up voltage inside the PCM. The FPM circuit will go high if, with the key ON and the fuel pump commanded OFF, the FPM/FP PWR circuit loses its path to ground through the fuel pump. The FPM circuit will also go high if the FPM/FP PWR circuit is shorted to power.
Inertia fuel shutoff (IFS) switch not reset or electrically open

Poor fuel pump ground

P0243 Ч Supercharger (Boost) Bypass Solenoid Circuit Malfunction The PCM monitors the supercharger (boost) bypass (SCB) solenoid circuit for an electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified SCB solenoid duty cycle (100% or 0%) by PCM command. VPWR circuit open to SCB solenoid
SCB solenoid circuit shorted to PWR GND or CHASSIS GND
Damaged SCB solenoid

P0298 Ч Engine Oil Over Temperature Condition Indicates the Engine Oil Temperature Protection strategy in the PCM has been activated. This will temporarily prohibit high engine speed operation by disabling injectors, therefore reducing the risk of engine damage from high engine oil temperature. Note: On engines which are equipped with an oil temperature sensor, the PCM reads oil temperature to determine if it is excessive. When an oil temperature sensor is not present, the PCM uses an oil algorithm to infer actual temperature. Engine shutdown strategy function is the same on vehicles with and without oil temperature sensors. Very high engine rpm for extended period of time.
Over-heating condition.
Malfunction EOT sensor or circuit (vehicles w/EOT sensor).
Base engine concerns.
Engine operating in high rpm range, due to improper gear selection. May cause Lack/Loss of Power or Surge customer concern.

P0300 Ч Random Misfire The random misfire DTC indicates multiple cylinders are misfiring or the PCM cannot identify which cylinder is misfiring. Camshaft position sensor (CMP)
Low fuel: less than 1/8 tank
Stuck open EGR valve
Blocked EGR passages
One or more EGR passages may be blocked or partially blocked. If this is the case the Misfire Detection Monitor will indicate the EGR port to check for possible blockage.

P0301 through P0310 Ч Misfire Detection Monitor The misfire detection monitor is designed to monitor engine misfire and identify the specific cylinder in which the misfire has occurred. Misfire is defined as lack of combustion in a cylinder due to absence of spark, poor fuel metering, poor compression, or any other cause. Ignition system
Fuel injectors
Running out of fuel
EVAP canister purge valve
Fuel pressure
Evaporative emission system
Base engine
The MIL will blink once per second when a misfire is detected severe enough to cause catalyst damage. If the MIL is on steady state, due to a misfire, this will indicate the threshold for emissions was exceeded and cause the vehicle to fail an inspection and maintenance tailpipe test.

P0320 Ч Ignition Engine Speed Input Circuit Malfunction The ignition engine speed sensor input signal to PCM is continuously monitored. The test fails when the signal indicates that two successive erratic profile ignition pickup (PIP) pulses have occurred. Loose wires/connectors.

The DTC indicates that two successive erratic PIP pulses occurred.

P0325 Ч Knock Sensor 1 Circuit Malfunction (Bank 1) See DTC P0326

P0326 Ч Knock Sensor 1 Circuit Range/ Performance (Bank 1) The knock sensor detects vibrations upon increase and decrease in engine rpm. The knock sensor generates a voltage based on this vibration. Should this voltage go outside a calibrated level a DTC will set. Knock sensor circuit short to GND
Knock sensor circuit short to PWR
Knock sensor circuit open

P1157 Ч Lack of HO2S-22 Switch, Sensor Indicates Lean See DTC P1137

P1158 Ч Lack of HO2S-22 Switch, Sensor Indicates Rich See DTC P1137

P1168 Ч Fuel Rail Pressure Sensor in Range But Low The comprehensive component monitor (CCM) monitors the FRP pressure for acceptable fuel pressure. The test fails when the fuel pressure falls below a calibrated value. Low fuel pressure
Damaged FRP sensor
Excessive resistance in circuit
Low or no fuel
A FRP PID value below 551 kpa (80 psi) indicates a failure
Low or no fuel
A FRP PID value greater than 896 kpa (130 psi) indicates a failure



P1169 Ч Fuel Rail Pressure (FRP) Sensor in Range But High The comprehensive component monitor (CCM) monitors the FRP pressure for acceptable fuel pressure. The test fails when the fuel pressure falls below or exceeds a minimum/maximum calibrated value for a calibrated period of time. High fuel pressure
Low fuel pressure
Damaged FRP sensor
Excessive resistance in circuit

P1180 Ч Fuel Delivery System Ч Low The PCM receives fuel tank pressure (FTP) information from the natural gas module (NG), which uses the information to infer fuel rail pressure (FRP). The test fails when the inferred pressure is less than a minimum calibrated value. Restriction in the fuel line
Plugged fuel filter

P1181 Ч Fuel Delivery System Ч High The PCM receives fuel tank pressure (FTP) information from the natural gas module (NG), which uses the information to infer fuel rail pressure (FRP). The test fails when the inferred pressure is higher than a maximum calibrated value. Fuel pressure regulator

P1183 Ч Engine Oil Temperature (EOT) Sensor Circuit Malfunction Indicates EOT circuit became intermittently open or shorted while engine was running. Damaged harness
Damaged sensor
Damaged harness connector
Damaged PCM
EOT V PID reading less than 0.2 volts with key ON a
