DTC P0200 [MZR-CD (RF Turbo)]

BME010200200W01

DTC P0200 | Fuel injector circuit malfunction
--- | ---
DETECTION CONDITION | • PCM monitors injection confirmation signal from IDM while engine is running. If injection confirmation signal is not input normally, PCM determines fuel injector circuit malfunction.
POSSIBLE CAUSE | • IDM • Connector or terminal malfunction • Short to GND in wiring between IDM terminal 2B and PCM terminal 30 • Short to GND in wiring between IDM terminal 2C and PCM terminal 42 • Short to GND in wiring between IDM terminal 2D and PCM terminal 44
• Short to GND in wiring between IDM terminal 2E and PCM terminal 45
• Short to GND in wiring between IDM terminal 2F and PCM terminal 43
• Short to power circuit in wiring between IDM terminal 2B and PCM terminal 30
• Short to power circuit in wiring between IDM terminal 2C and PCM terminal 42
• Short to power circuit in wiring between IDM terminal 2D and PCM terminal 44
• Short to power circuit in wiring between IDM terminal 2E and PCM terminal 45
• Short to power circuit in wiring between IDM terminal 2F and PCM terminal 43
• Open circuit in wiring between IDM terminal 2B and PCM terminal 30
• Open circuit in wiring between IDM terminal 2C and PCM terminal 42
• Open circuit in wiring between IDM terminal 2D and PCM terminal 44
• Open circuit in wiring between IDM terminal 2E and PCM terminal 45
• Open circuit in wiring between IDM terminal 2F and PCM terminal 43
• PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Check for related Service Information availability. • Is any related repair information available? | Yes | Perform repair or diagnosis according to available Service Information. • If vehicle is not repaired, go to next step.
No | Go to next step.
2 | FOLLOW OTHER DETECTED DTC FIRST • Turn engine switch to OFF. • Start engine. • Has P0300 been detected? | Yes | Go to DTC P0300 inspection. (See DTC P0300 [MZR-CD (RF Turbo)].)
No | Go to next step.
3 | INSPECT POOR CONNECTION OF IDM CONNECTOR • Turn engine switch to OFF. • Inspect for poor connection (damaged, pulled-out terminals, corrosion, etc.). • Is there any malfunction? | Yes | Repair or replace suspected terminal, go to Step 9.
No | Go to next step.
4 | INSPECT IDM CIRCUIT FOR SHORT TO GND • Turn engine switch to OFF. • Inspect continuity between following harnesses:

  - IDM terminal 2B and body GND.
  - IDM terminal 2C and body GND.
  - IDM terminal 2D and body GND.
  - IDM terminal 2E and body GND.
  - IDM terminal 2F and body GND.

• Is there continuity?
Yes
Repair or replace harness for short to GND, go to Step 9.
No | Go to next step.
5 | INSPECT IDM CIRCUIT FOR SHORT TO POWER • Turn engine switch to ON (Engine OFF). • Inspect voltage between following harnesses:

  - IDM terminal 2B and body GND.
  - IDM terminal 2C and body GND.
  - IDM terminal 2D and body GND.
  - IDM terminal 2E and body GND.
  - IDM terminal 2F and body GND.

• Is voltage below 1.0 V?
Yes
Go to next step.
No | Repair or replace harness for short to power, go to Step 9.
6 | INSPECT IDM • Inspect IDM. (See INJECTOR DRIVER MODULE (IDM) INSPECTION [MZR-CD (RF Turbo)].) • Is there any malfunction? | Yes | Replace IDM, go to Step 9.
No | Go to next step.
7 | INSPECT POOR CONNECTION OF PCM CONNECTOR • Turn engine switch to OFF. • Inspect for poor connection (damaged, pulled-out terminals, corrosion, etc.). • Is there any malfunction? | Yes | Repair or replace suspected terminal, go to Step 9.
No | Go to next step.
8 | INSPECT IDM CIRCUIT FOR OPEN • Turn engine switch to OFF. • Inspect continuity between following harnesses:

  - IDM terminal 2B and PCM terminal 30.
  - IDM terminal 2C and PCM terminal 42.
  - IDM terminal 2D and PCM terminal 44.
  - IDM terminal 2E and PCM terminal 45.
  - IDM terminal 2F and PCM terminal 43.

• Is there continuity?
Yes
Go to next step.
No | Repair or replace harness for open, go to next step.
9 | VERIFY TROUBLESHOOTING OF DTC P0200 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear DTC from PCM memory using WDS or equivalent. • Start engine. • Is same DTC present? | Yes | Replace PCM, go to next step. (See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
No | Go to next step.
10 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [MZR-CD (RF Turbo)].) • Is there any DTC present? | Yes | Go to applicable DTC inspection. (See DTC TABLE [MZR-CD (RF Turbo)].)
No | Troubleshooting completed.
