Cylinder 8 Injector A Circuit

Causes
- Open or shorted wiring to cylinder 8 injector
- Corroded or loose connector at injector
- Failed fuel injector (stuck open/closed or intermittent)
- Faulty injector driver in the PCM/ECM
- Poor or missing ground(s) for the injector circuit
- Blown fuse or faulty fuel/injector power relay
Symptoms
- Check Engine Light (MIL) illuminated
- Rough idle or engine misfire on cylinder 8
- Loss of power, hesitation, or poor acceleration
- Higher fuel consumption and increased emissions
- Hard starting or no-start in severe open-circuit cases
What to check
- Read and record freeze frame and all stored codes with a scan tool
- Verify code is current (not pending) by clearing codes and re-running engine
- Visual inspection of wiring and connectors at cylinder 8 injector for damage, corrosion, or pin push-out
- Check fuses and fuel/injector power relay for continuity and proper operation
- Measure injector resistance with meter and compare to vehicle spec
- Back-probe injector connector while cranking/idle to observe supply and driver signal
Signal parameters
- Injector supply (reference) voltage: approximately battery voltage (~11–14 V) with ignition ON (verify vehicle spec)
- Injector driver output: pulsed ground or pulsed positive depending on design (on-pulse typically pulls toward 0 V when ground-switched)
- Injector resistance: varies by design — common ranges: low-impedance 2–6 Ω, high-impedance 12–16 Ω (consult vehicle spec)
- Pulse width: typically 1–10 ms at idle, increases with load — frequency proportional to RPM
- Expected idle waveform: steady pulsed waveform with consistent amplitude and pulse width between cylinders (use oscilloscope)
Diagnostic algorithm
- Retrieve freeze frame and all codes; note any related misfire codes (e.g., P0308). Clear codes and attempt to re-create. 2) Visually inspect the harness, connector, and pins at injector 8; repair any physical damage and secure connector. 3) Verify injector supply voltage at the connector with ignition ON (battery voltage). 4) Measure injector coil resistance with meter; compare to manufacturer specification. Replace injector if out of range. 5) Back-probe the injector while cranking/running: confirm the driver toggles (pulses) and that supply remains present. Use oscilloscope if possible to view waveform. 6) Wiggle test wiring and connector while observing signal to catch intermittent faults. 7) Swap injector 8 with another known-good injector (if identical) and run engine; if code follows injector, replace injector. 8) If problem remains, trace wiring to ECM for opens/shorts (to battery or ground) and repair. 9) Check related fuses, relays, and engine grounds; repair as needed. 10) If wiring and injector are good, perform ECM output driver bench test or replace ECM per vehicle-specific procedures.
