Cylinder 6 Injector A Circuit

Completed 100%
Page language: EN

Causes

  • Open or shorted wiring between ECM and cylinder 6 injector
  • Poor or corroded connector at the injector or ECM
  • Failed or stuck injector (electrical or mechanical)
  • Blown fuse or faulty power feed/relay to injectors
  • Faulty ECM/PCM injector driver circuit
  • Aftermarket parts or recent repairs with incorrect wiring

Symptoms

  • Check Engine Light (MIL) illuminated
  • Rough idle or misfire localized to cylinder 6
  • Reduced engine power, hesitation or stumbling under load
  • Poor fuel economy and increased emissions
  • Possible hard starting or stumble during acceleration

What to check

  • Retrieve trouble codes and freeze frame data with a scan tool; note freeze frame and readiness
  • Visually inspect injector harness, connector, and pins at cylinder 6 for corrosion, damage or oil intrusion
  • Check for any blown fuses or failed injector relay that supplies fuel injectors
  • Backprobe injector connector with key ON to confirm reference voltage/power is present
  • Measure injector coil resistance and compare to manufacturer spec
  • Use a noid light or scan tool to confirm injector is being pulsed when commanded

Signal parameters

  • Typical injector coil resistance: high-impedance 12–16 Ω, low-impedance 2–5 Ω (check OEM spec for exact value)
  • Reference supply: battery voltage (~B+) present at injector power pin with key ON
  • Driver output: ECM switches injector to ground; voltage at driver pin should drop near 0 V when commanded
  • Pulse width: typical 1–5 ms at idle; varies with load and RPM (scan tool will show pulse width)
  • Duty cycle: low at idle, increases with load; near 100% only at high demand
  • Oscilloscope waveform: sharp ground-side switching edges; look for missing pulses, shorted waveform, or noisy signal

Diagnostic algorithm

  1. Confirm code and record freeze frame data. Clear codes and attempt to reproduce.
  2. Perform a visual inspection of wiring and connectors at cylinder 6 injector and ECM for obvious damage, corrosion or oil intrusion.
  3. With ignition OFF, unplug the injector connector and inspect pins; check for bent or pushed-out terminals.
  4. Measure injector coil resistance at the injector pins; compare to OEM spec. Replace injector if open or out-of-spec.
  5. With key ON (engine OFF) backprobe the connector to verify battery voltage on the power feed circuit. If no voltage, check fuse/relay/power distribution.
  6. Command the injector ON using a scan tool while monitoring the connector with a noid light or oscilloscope to confirm pulsing and waveform shape.
  7. While commanding the injector, measure voltage at the driver pin; it should switch to near ground when energized. If it stays at battery, suspect driver open; if stuck at ground, suspect short to ground.
  8. Check continuity between the injector connector and the ECM injector driver pin; inspect for short to battery or ground and for high resistance/opens.
  9. Swap the suspect injector with a known good injector of the same type. If the code or misfire follows the injector, replace the injector.
  10. If wiring and injector test good but code persists, inspect ECM connector and grounds. Repair damaged wiring or connector terminals as needed.
  11. As a last step, if all wiring and injector tests are good and fault remains, consider ECM/PCM driver failure and consult manufacturer procedures for ECM testing/replacement.

Likely causes

  • Damaged connector or wiring (broken wire, pin corrosion, rodent damage)
  • Injector shorted internally or open (failed injector coil)
  • Poor pin contact at injector harness connector
  • Injector fuse/relay or shared power feed open
  • ECM driver fault (less common) or PCM software/firmware issue

Fault status

⚠️ Status
P0206 - Cylinder 6 Injector A Circuit: ECM detected abnormal electrical condition (open, short, excessive/insufficient current or voltage) in the injector circuit for cylinder 6.

  2. Perform a visual inspection of wiring and connectors at cylinder 6 injector and ECM for obvious damage, corrosion or oil intrusion.
  3. With ignition OFF, unplug the injector connector and inspect pins; check for bent or pushed-out terminals.
  4. Measure injector coil resistance at the injector pins; compare to OEM spec. Replace injector if open or out-of-spec.
  5. With key ON (engine OFF) backprobe the connector to verify battery voltage on the power feed circuit. If no voltage, check fuse/relay/power distribution.
  6. Command the injector ON using a scan tool while monitoring the connector with a noid light or oscilloscope to confirm pulsing and waveform shape.
  7. While commanding the injector, measure voltage at the driver pin; it should switch to near ground when energized. If it stays at battery, suspect driver open; if stuck at ground, suspect short to ground.
  8. Check continuity between the injector connector and the ECM injector driver pin; inspect for short to battery or ground and for high resistance/opens.
  9. Swap the suspect injector with a known good injector of the same type. If the code or misfire follows the injector, replace the injector.
  10. If wiring and injector test good but code persists, inspect ECM connector and grounds. Repair damaged wiring or connector terminals as needed.
  11. As a last step, if all wiring and injector tests are good and fault remains, consider ECM/PCM driver failure and consult manufacturer procedures for ECM testing/replacement.

Likely causes

  • Damaged connector or wiring (broken wire, pin corrosion, rodent damage)
  • Injector shorted internally or open (failed injector coil)
  • Poor pin contact at injector harness connector
  • Injector fuse/relay or shared power feed open
  • ECM driver fault (less common) or PCM software/firmware issue

Fault status

⚠️ Status
P0206 - Cylinder 6 Injector A Circuit: ECM detected abnormal electrical condition (open, short, excessive/insufficient current or voltage) in the injector circuit for cylinder 6.
🟡 Repair difficulty: Medium

LAND ROVER P — Powertrain

Cylinder with injector circuit fault 6

Views: UK: 2 EN: 9 RU: 7
AI status
Completed
ready
Completed 100%
Page language: EN

Causes

  • Open or shorted wiring between ECM and cylinder 6 injector
  • Poor or corroded connector at the injector or ECM
  • Failed or stuck injector (electrical or mechanical)
  • Blown fuse or faulty power feed/relay to injectors
  • Faulty ECM/PCM injector driver circuit
  • Aftermarket parts or recent repairs with incorrect wiring

Symptoms

  • Check Engine Light (MIL) illuminated
  • Rough idle or misfire localized to cylinder 6
  • Reduced engine power, hesitation or stumbling under load
  • Poor fuel economy and increased emissions
  • Possible hard starting or stumble during acceleration

What to check

  • Retrieve trouble codes and freeze frame data with a scan tool; note freeze frame and readiness
  • Visually inspect injector harness, connector, and pins at cylinder 6 for corrosion, damage or oil intrusion
  • Check for any blown fuses or failed injector relay that supplies fuel injectors
  • Backprobe injector connector with key ON to confirm reference voltage/power is present
  • Measure injector coil resistance and compare to manufacturer spec
  • Use a noid light or scan tool to confirm injector is being pulsed when commanded

Signal parameters

  • Typical injector coil resistance: high-impedance 12–16 Ω, low-impedance 2–5 Ω (check OEM spec for exact value)
  • Reference supply: battery voltage (~B+) present at injector power pin with key ON
  • Driver output: ECM switches injector to ground; voltage at driver pin should drop near 0 V when commanded
  • Pulse width: typical 1–5 ms at idle; varies with load and RPM (scan tool will show pulse width)
  • Duty cycle: low at idle, increases with load; near 100% only at high demand
  • Oscilloscope waveform: sharp ground-side switching edges; look for missing pulses, shorted waveform, or noisy signal

Diagnostic algorithm

  1. Confirm code and record freeze frame data. Clear codes and attempt to reproduce.
  2. Perform a visual inspection of wiring and connectors at cylinder 6 injector and ECM for obvious damage, corrosion or oil intrusion.
  3. With ignition OFF, unplug the injector connector and inspect pins; check for bent or pushed-out terminals.
