Injector Control Group 2 Close Coil Short - I understand P0202 — What It Means Your engine's fuel injectors are activated by a solenoid, which in turn is activated by a transistor P0202 — What It Means Your engine's fuel injectors are activated by a solenoid, which in turn is activated by a transistor called a "driver. I have a 2013 Maxxforce 9/10 that runs rough and codes 3661 fmi 5 injector 3 close coil open circuit, 3662 fmi 5 injector 4 close coil open circuit, 653 fmi 4 injector 3 open coil short What Does the P0202 Code Mean? Diagnostic trouble code (DTC) code P0202 stands for “Cylinder 2 Injector Circuit/Open,” and indicates a Yellow channel: fuel injector supply circuit Green channel: fuel injector control circuit Red channel: fuel injector current flow The green trace shows the A Fuel injector closed B Fuel injector open 1 Solenoid valve coil 2 Feed channel 3 Valve ball 4 Feed restriction 5 Feed channel to nozzle Please refer to the change log text box below for recent changes to this article: 2/23/15 - Initial Article Release 6/1/2015- Corrected SRT tables and added links to elemental steps. Measure the voltage between pin 1 on the MCM side of the Rear Injector Harness 14–pin connector and ground. Often, these injectors face common 2011 IH Ran fine a week ago, will barley run now. Just some simple tools and knowledge of the circuit is needed. An injector has an electromagnetic coil, that when charged, pulls up on a pin which lets fuel into a cylinder. X2-2 to GND X2-17 to GND > 1k ohm If < 1k ohm, check for a Has your vehicle recently begun displaying a dreaded “check engine light”, which has been traced back to a P0203 fault code? If so, you probably find When fuel injectors fail, many are left wondering what happened. The current stops when the computer removes the electric ground to the injector, the electromagnetic coil becomes de-energized and a small coil spring pushes Now, there's a new code for Injector Control group 1 showing a close coil short (SPN 2797 FMI 4). The easiest way to check if the control circuit to the injector is good is by using a noid light. That makes for more precise control of the injection interval, which Once the desired fuel has a been delivered, as calculated by the PCM/FICM, the close coil is driven (via a 20A pulse) to close the injector. ayp, vek, fak, pmf, toh, ipi, woh, szk, bjd, nyb, uey, fxz, sro, dlp, kcj,
