The Injector Driver Module inside my computer with ECU code YDH1 has decided that it does not want to work properly anymore, and keeps giving me Check Engine Code P0206, Cylinder 6 Open Injector Circuit. This means that the PCM had detected a malfunction in one of the injector circuits. Conversely, when a fuel injector is commanded “on” by the PCM, it expects to see the voltage pulled low on the driver circuit If it doesn’t see this expected. I have recently taken my 2014 1. The parallel input data is logically ORed with the corresponding SPI input data register contents. Here's a link to the youtube video I posted of me doing this test. P0203 - Injector 3 Control Circuit Thanks. 2000 mitsubishi eclipse ecm engine control module ECM , ECU , Engine Control Modules , TCM , TCU , Transmission Control Modules , PCM , Powertrain Control Modules , IDM , Injector Driver Modules , FICM , Fuel Injector Control Modules , Diesel ModulesClick on below makes to browse products. The car starts but runs very rough for a couple seconds and cuts out. When the PCM sees that the voltage from cylinder 6 is outside the normal operating range, this code will be stored in its memory. 2) Intermittent cylinder misfires. As you can see on attached photo, I've find defected burst transistor on the right. Are you following everything I've told you to do. P0201 Cylinder 1 Injector Circuit / Open P0202 Cylinder 2 Injector Circuit / Open P0203 Cylinder 3 Injector Circuit / Open P0204 Cylinder 4 Injector Circuit / Open 2002 Transit mk6 2. Make sure that your PCM is connected to your battery, and that there’s no rust on the PCM itself or on the. Fuel Injectors, whether Throttle Body Injection (TBI), Port Fuel Injection (PFI) or Direct Injection, are controlled by the vehicle's onboard computer (Powertrain Control Module (PCM) or Engine Control Unit (ECU), to meter and atomize the correct amount of fuel entering the engine under all operating conditions. Chances are good that the circuit it's shorted to would be the same ASD output wiring, so your circuit resistance when checked at the Pin 6 to 13 locations would be essentially zero. Fuel Injectors 4,5,6 are grouped together on bank 2. A P0204 is likely one of 3 things, either the #4 injector itself, the circuit to (+) or from (-) the injector is shorted or . Possible Fuel Contamination or Wrong Fuel in Tank. The PCM expects to see this spike and if present it knows the fuel injector circuitry is good. P0973 - PCM detects an open or short to ground in the 1-2 SS valve circuit. Basically, wiring from ECU to injectors tested OK, and wiring from ECU to overloading the injector driver circuits, as Wade suggested. P0206 is usually caused by a bad fuel injector or wiring issue. If it is, measure the resistance across the #4 injector driver circuit. This completes the circuit and fuel is sprayed into the cylinder. DTC P0204 Injector 4 Control Circuit. DTC : PCM_P0282P : Misfire/Injector Driver Circuit Operation P : Misfire/Injector Driver Circuit Operation P1 : PRELIMINARY DIAGNOSIS P2 : DIAGNOSTIC TROUBLE CODES (DTCS) P0261, P0264, P0267, P0270, P0273, P0276, P0279, OR P0282 P3 : CHECK FOR SHORTS IN THE INJECTOR P4 : CHECK THE FUEL INJECTOR CIRCUITS FOR AN OPEN. If there is a low resistance on the wire for the #4 injector only, then the driver transistor in the PCM or the wire to it has shorted out. Will confirm the pin position when I have time. Fuse box diagram (fuse layout), location and assignment of fuses and relays Ford E150, E250, E350, E450, E550 (Van, Wagon, Cutaway, Stripped, Chassis Cab) 1997-2008. Pulled the cover off the loom for the fuel injector harness, and that's when I think I found the problem. Malfunction of the Fuel Injector, Malfunction of the PCM Fuel Injector driver circuit, Defective wiring/connections in the Fuel Injector wiring harness, Defective Fuel Injector power circuit(s) P0203: Fuel injector failure, Powertrain Control Module (PCM) failure, Wiring issue: P0205:. This is an open circuit test procedure using a test light and a voltmeter. When it's time to spray fuel into the cylinder, the PCM grounds the other terminal and completes a circuit, which activates the driver and solenoid to open the.
