SOURCE: Check engine light comes on. p0171 and p0351 codes found

From Lusty Kid:

I know the economy is bad, but change all of the plugs. Check your PCV Valve hose, 150 rottens them out allowing air to be sucked in, thus all kinds of codes.

Depending on mileage. Dismount the EGR valve and clean passages. If you are really good dismount the throtle position sensor body and clean out passages with Choke Cleaner., dismount where the EGR valves connects to the engine, clean out passages. Also check the hose thats behind this mounting to ensure is not clogged. If clogged clean it out. If not replace it. Is about 1.5 ft. long, connects to the PCV Valve Hose.

When is the last time you change your harness. Can't remember??? Replace it. Good Luck

Might check the coolant sensor. Make sure it is reading correctly. If it is still reading cold on your coolant sensor it will tell the computer to run as if it were cold telling the computer to send more fuel when in fact it doesnt need any because the engine is already warmed up.

sounds alot the the pcm it controls the fuel pump and ign system but the anti theft would keep it from starting because the key has a transponder in it programmed for that vehicle and that would kill all ign if triggered

SOURCE: P0740 T Converter Clutch Circuit Malfunction

The transmission fluid could be in need of a change, certain parts in the transmission depend upon clean fluid to move properly, this could cause the pressure sensor to fail and engage the torque converter to lock up at the right time. Timing is counted with the computer and it will flash lights when there is a problem.

That code is: Fuel Pump Primary Circuit Malfunction. Could it be the wires are not on tight or one is shorted? Check wiring very carefully.

P0230 fault - citroen xsara picasso 2001 2.0HDI - not fuel pump or relay changed - intermittent cutting out on car - can drive 30 / 5 / 15 miles before this occurs


code p 0230 refers to fuel pump relay---circuit malfunction===causes --wiring---fuel pump relay-- ECM
check wiring for bad connections
replace the ECM with a known good unit as it may be breaking down electronically in the circuit that controls the pump relay
Check the pressure regulator as well as it reports to the ECM to shut off the pump relay when the fuel pressure is reached and not being used

HI, FORD MUSTANG 2013 V6 I CLEANed THE CATalytic CONVERTER, I get CODE P0420 P0230 ANYBoDY CAN HELP ME THANKS, A LOT. HAPPY NEW YEAR


P0420 Catalyst System Efficiency Below Threshold (Bank 1)

P0230 - Fuel Pump Primary Circuit Malfunction NOTE: For natural gas applications, the following description applies to the fuel shutoff valve (FSV) circuit.
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.
An open circuit or short to ground can only be detected with the fuel pump commanded OFF.
A short to power can only be detected with the fuel pump commanded ON.
During KOEO and KOER self-test, the fuel pump output command will be cycled ON and OFF.

Chevy Silverado 2002 2500 shows trouble code, P0230, and P0300


P0230 - Fuel Pump Primary Circuit Malfunction Symptoms - Engine Light ON (or Service Engine Soon Warning Light) Possible causes - Blown Fuel Pump fuse
- Open Fuel Pump Monitor Circuit
- Faulty Fuel Pump Relay
- Damaged ECM. P0230 Description The Engine Control Module (ECM) provides ignition positive voltage to the coil side of the fuel pump relay. When the ignition switch is first turned ON, the ECM energizes the fuel pump relay, which applies power to the fuel pump. The ECM enables the fuel pump relay as long as the engine is cranking or running, and crankshaft reference pulses are received. If no crankshaft reference pulses are received, the ECM de-energizes the fuel pump relay after 2 seconds. The ECM monitors the voltage on the fuel pump relay control circuit.

Kia 03 Spectra fuel OBD code P0230 primary circuit failure. Relay does not pick up Fuse is good. No spark on the ignition - relay does not pick up fuse is good. What is in the primary circuit and where...


Unfortunately there are no mechanical fixes available because that trouble code indicates a malfunction somewhere in the electrical circuit for the fuel pump and that would include wiring from the battery to the pump, the fuel pump control module and the and the car's brain, the ECM. It can be a loose connection, but if one is not easily found, then the problem has to be tested with special electrical testing equipment. More information is available but I can't post an illustration of the troubleshooting for this Diagnostic Trouble Code.

There is, however, an illustration that describes that troubleshooting at this location currently:

P0230 - Fuel Pump Primary Circuit Malfunction

Check the wiring to these components first, power and earth etc, if wiring is ok you may have faulty components, especially the primary lift pump in the fuel tank, these are famous for failing.

Keep us updated.
