How to find a p0261 circuit low code?
My 01 Volkswagen Jetta GLS 2.0 My car pulled up 7 codes today PO261 PO264 PO267 PO270 PO418 PO445 P1472 I Don’t know if I caused it from taking out the fuse for my radio because my tape is stuck in it and won’t stop running but says no tape? But the fuse I took out was #42 25a If anyone could h… Need more help with a p0261 code?
How does the FICM control the fuel injector?
To drive the fuel injector, the FICM produces two control signals for each injector. The open coil is driven (via a 20A pulse) to open the injector. This shifts the spool valve in the injector to the open state. Once this has taken place, high pressure oil is directed on top of the injector intensifier piston.
How to diagnose a 6.0 power stroke FICM?
0 PowerStroke FICM OBDII FAULT CODE DIAGNOSTICS. 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. P0270 Cylinder 4 Injector Circuit Low. P0273 Cylinder 5 Injector Circuit Low
What are the codes for shorted coils in FICM?
Open coils produce low current which sets the injector circuit low codes (ie. P0261, P0264, … , P0282). Shorted coils (side shorts) or short to grounds produce high current which sets the injector circuit high codes (ie. P0262, P0265, …, P0283).
Where are the FICM part numbers on a fuel injector?
Note: International FICM part numbers are located on a label on the connector side of the module. To drive the fuel injector, the FICM produces two control signals for each injector. The open coil is driven (via a 20A pulse) to open the injector.

How does the FICM work with the ignition switch?
It uses engine speed and position signals (*CKPO, *CMPO) to determine when the injectors need to be activated. The ignition switch provides *KEYPWR to the FICM. Once this signal is detected by the FICM, the *MPR output of the FICM will engage the FICM relay. This in turn provides the *FICM PWR and *FICM Logic PWR voltages to the FICM.
