Will a bad Ficm cause a misfire?
Will a bad Ficm cause a misfire?
A failing FICM can cause all sorts of problems, but one of the most common symptoms is an engine that is hard to get started, especially when the engine is cold or has sat overnight. Another symptom commonly seen is the engine is running rough or misfiring all of the time, or after the engine is warmed up.
What does the 58v Ficm do?
The higher output voltage of our 58v FICM forces the fuel injector to open more quickly, which allows the fuel injector to flow slightly more fuel than the lower/stock voltage unit. The quicker action of the fuel injector also slightly advances the injection timing. We also eliminate that annoying injector post buzz.
How do you check Ficm voltage on a 6.0 Powerstroke?
Check the FICM Output Voltage: If you have a scan tool you can just pull up FICM voltage from the menu and look at it there. The Auto Enginuity scan tool we use in the shop will read the voltage. The voltage should be in the 46-48 volt range with the engine running. If the voltage drops lower, the FICM needs replaced.
How do you know if your Ficm is bad?
You should have a minimum of 45 volts to be within specification with the ignition key in the RUN position, cranking and engine running. Any voltage reading below 45 volts indicates a bad FICM and will need to be replaced. If you receive a 0 voltage reading while cranking you may have a bad FICM fuse and or relay.
What does the PCM control on a 6.0 Powerstroke?
The Powertrain Control Module, or simply PCM, is the vehicle’s primary computer system. Integration between the 6.0L Power Stroke engine and 5R110W TorqShift transmission is the responsibility of the PCM, and it’s what keeps the two ticking in unison. PCM failures are not remarkably common, however they do occur.
What are the symptoms of a Ford Power Stroke FICM failure?
Ford 6.0 Power Stroke FICM Diagnostics The 6.0 Power Stroke FICM is often mis-diagnosed and needlessly replaced. Calibration concerns, powertrain component faults and FICM malfunctions may produce similar drivability concerns. NOTE: The most common symptoms of a failed FICM are: NO START or CONSTANT MISFIRE AT ALL ENGINE TEMPERATURES.
What are the symptoms of a failing FICM?
What are the symptoms of a failing 6.0 FICM? A failing FICM can cause all sorts of problems, but one of the most common symptoms is an engine that is hard to get started, especially when the engine is cold or has sat overnight.
How do you turn off the FICM on a power stroke?
If something wrong is detected, the two CMPO and CKPO outputs going to the FICM can be turned off by the PCM/TCM thus disabling fueling of the FICM. This video will show you how to easily diagnose and if necessary replace the Fuel Injection Control Module (FICM) on your 6.0 Power Stroke.
What are the fault codes for a power stroke?
The below fault codes may help point you in the right direction when diagnosing the 6.0 Power Stroke FICM: P0261 Cylinder 1 Injector Circuit Low P0264 Cylinder 2 Injector Circuit Low P0267 Cylinder 3 Injector Circuit Low
