Jul 10, 2020 · Another cause of the P0200 code that can cause an injector circuit malfunction is an open or shorted injector. The electrical circuit is “open” and not closed, meaning that the electrons will not flow, and be due to an injector coil itself being broken. Similar to that an injector wiring harness being open or short and causing the injector ... Fuel injector 4 harness is open or shorted Fuel injector 4 circuit poor electrical connection The P0304 code means that the cylinder 4 is misfiring or is randomly misfiring.Nov 22, 2019 · If you are using a generic (not vehicle manufacturer specific) code reader; then you can expect to see codes beginning with P02. For example, a fault with an injector in cylinder one would give a code of P0201. These are all fuel & air metering injector circuit related codes. Listen To The Fuel Injectors The injectors are set up to run alternately with the 'injector staging' parameter in MegaTune. For example, on an independent runner 4 cylinder engine you set the MegaSquirt ® to 2 squirts/alternating. Each runner will have 1 injector from each bank squirting into it. 00260 P0758 Shift Solenoid 2 - Open Circuit or Short to Ground or B+ (N89) 00261 ABS Inlet Valve - Rear (N103) 00262 P0763 Shift Solenoid 3 - Open Circuit or Short to Ground or B+ (N90) 00263 Transmission 0107 - Mechanical/Hydraulic Malfunction 00264 P0748 Shift Solenoid 4 - Open Circuit or Short to Ground or B+ (N91)
