What is the diagnostic code for fuel pump secondary circuit high?
What is the diagnostic code for fuel pump secondary circuit high?
Cost of diagnosing the P0232 code. P0232 is a diagnostic trouble code (DTC) for “Fuel Pump Secondary Circuit High”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What causes low voltage fuel pump secondary circuit?
The ECM monitors the fuel pump relay secondary circuit for voltage. If voltage drops below a certain threshold, it will set DTC P0231, which is defined as “Low Voltage Fuel Pump Secondary Circuit.” What are the common causes of code P0231 ?
What should the short circuit be on a fuel pump?
Short Circuit Check – With the fuel pump relay removed, you should measure at least 4 Ω through the pump to ground. If you measure <4 Ω, you’ll have to find and repair the short circuit. Repeat the test with the fuel pump disconnected. If the short circuit persists, the short is somewhere between the relay and ground.
What does the code p0232 mean on a fuel pump?
Fuel Pump Secondary Circuit High What the P0232 code means P0232 is a generic OBD-II code that is triggered when the engine control module (ECM) detects that the secondary circuit to the fuel pump has a high voltage when the fuel pump relay is turned off.

Where is the feedback circuit on a fuel pump?
When the PCM (powertrain control module) activates the fuel pump relay, voltage is supplied to the fuel pump and it pressurizes the fuel system. Some vehicles have a feedback on the fuel pump supply circuit. This is simply a circuit spliced into the voltage feed to the fuel pump. The splice is usually located close to the PCM.
How is the fuel pump powered by the PCM?
The fuel pump is powered by the fuel pump relay. When the PCM (powertrain control module) activates the fuel pump relay, voltage is supplied to the fuel pump and it pressurizes the fuel system. Some vehicles have a feedback on the fuel pump supply circuit. This is simply a circuit spliced into the voltage feed to the fuel pump.
What is the OBD code for fuel pump?
All our repairs are backed by our 12-month / 12,000-mile warranty. P0232 is a generic OBD-II code that is triggered when the engine control module (ECM) detects that the secondary circuit to the fuel pump has a high voltage when the fuel pump relay is turned off.
What causes a fuel filter to become restricted?
Inlet Restriction – Is commonly caused by a restricted primary fuel filter. The primary fuel filter may become restricted due to normal filtering operation or fuel gelling when operating in cold ambient temperatures. Fuel filter life is very dependent on the quality of fuel used.
What happens to the fuel system on a 6.7L diesel?
Fuel contamination on 6.7L diesel engines can damage fuel system components including the High Pressure (HP) fuel injection pump and fuel injectors.
When does the fuel pump code come on?
The code will be set if a low voltage on the control circuit of the fuel pump relay is detected by the ECM. Engine Light ON (or Service Engine Soon Warning Light) The Engine Control Module ( ECM) provides ignition positive voltage to the coil side of the fuel pump relay.
What is the DTC for a fuel pump?
P0627 is a diagnostic trouble code (DTC) for “Fuel Pump “A” Control Circuit /Open”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $0.0.
What is the diagnostic code for fuel pump secondary circuit low?
P0231 is a diagnostic trouble code (DTC) for “Fuel Pump Secondary Circuit Low”.
All our repairs are backed by our 12-month / 12,000-mile warranty. P0232 is a generic OBD-II code that is triggered when the engine control module (ECM) detects that the secondary circuit to the fuel pump has a high voltage when the fuel pump relay is turned off.
Fuel Pump Secondary Circuit High What the P0232 code means P0232 is a generic OBD-II code that is triggered when the engine control module (ECM) detects that the secondary circuit to the fuel pump has a high voltage when the fuel pump relay is turned off.
How does the engine control module ( ECM ) detect the fuel pump?
The engine control module (ECM) detects the primary fuel pump circuit voltage as below specifications from the fuel pump relay to the ECM The fuel pump relay main power supply could be low from a blown fuel pump fuse or fusible link, or from a shorted fuel pump or circuit What are the symptoms of the P0230 code?
