    Did the engine stall?

    YES 

    Go to step 5 (diagnosis by parameter (MAF SENSOR)).

    NO 

    Go to step 4.

  4. On-board snapshot check

    -1. Check for a record of Engine Stall 2 in the on-board snapshot with the HDS.

    On-board Snapshot

    Is there an Engine Stall 2 record in the on-board snapshot?

    YES 

    Go to step 5 (diagnosis by parameter (MAF SENSOR)).

    NO 

    Go to step 17 (fuel system troubleshooting).

    NOTE:  If an engine stall on-board snapshot was not found, the snapshot may have been lost due to low 12 volt battery voltage or because of 12 volt battery disconnection or replacement.

  5. On-board snapshot check (MAF SENSOR):

    NOTE:  Use the on-board snapshot in the case of an intermittent failure, or use the snapshot in the case of reproducible failure.

    -1. Check for a record of Engine Stall 2 in the on-board snapshot or the recorded snapshot with the HDS.

    On-board Snapshot

    -2. Select the MAF SENSOR and ENGINE SPEED in the configuration list.

    Check the recorded snapshot or on-board snapshot parameters at the time of the engine stall, then compare the MAF SENSOR pattern from the charts, and determine the problem.

    Pattern Symptom (Diagnosis by parameter) Additional remarks
    Pattern 1 Poor connection of MAF SENSOR
    GHH428006Courtesy of HONDA, U.S.A., INC.
    		 If the engine stalls 1 - 2 seconds after MAF SENSOR shows "0" g/s the engine stall may be caused by a faulty MAF sensor, poor connection, or electrical noise in the MAF sensor signal.
    Pattern 2 MAF SENSOR normal
    GHH428007Courtesy of HONDA, U.S.A., INC.
    		 When the MAF SENSOR pattern matches ENGINE SPEED, the MAF sensor is normal.

    Which pattern is indicated?

    Pattern 1

    Check MAF sensor/IAT sensor 1 for loose terminals or poor connections. If the terminals and connections are OK, substitute a known-good MAF sensor/IAT sensor 1 .

    Pattern 2

    Go to step 6 (diagnosis by parameter (ECT SENSOR 1)).

  6. On-board snapshot check (ECT SENSOR 1):

    NOTE:  Use the on-board snapshot in the case of an intermittent failure, or use the snapshot in the case of a reproducible failure.

    Pattern Symptom (Diagnosis by parameter) Additional remarks
    Pattern 1 ECT SENSOR 1 high
    GHH428008Courtesy of HONDA, U.S.A., INC.
    		 When ECT SENSOR 1 indicates about 176 deg.F (80 deg.C) or more when the engine is actually cold, ECT sensor 1 signal may be stuck high. If this occurs, the PCM may not properly compensate for cold engine operation, causing the engine to stall.
    Pattern 2 ECT SENSOR 1 normal
    GHH428009Courtesy of HONDA, U.S.A., INC.
    		 If actual engine temp is similar to ECT SENSOR 1, ECT sensor 1 is normal.

    Which pattern is indicated?

    Pattern 1

    Check for a short in the ECT sensor 1 circuit and a failure in ECT sensor 1.

    Pattern 2

    Go to step 7.

  7. ECT sensor 1 check

    -1. Turn the vehicle to the OFF (LOCK) mode.

    -2. Let the engine cool for 24 hours.

    -4. Turn the vehicle to the ON mode, but do not start the engine.

    -5. Check the parameter(s) below with the HDS.

    Signal Current conditions
    Values Unit
    ECT SENSOR 1    
    ECT SENSOR 2    

    Are the values of ECT SENSOR 1, ECT SENSOR 2, and the ambient temperature almost the same?

    YES 

    Go to step 8 (diagnosis by parameter (BATTERY)).

    NO 

    If the value of ECT SENSOR 1 is much higher (or lower) than that of ECT SENSOR 2 and the ambient temperature, check for the ECT sensor 1 circuit and a failure in ECT sensor 1.

    NOTE:  Use the on-board snapshot in the case of an intermittent failure, or use the snapshot in the case of a reproducible failure.

    -1. Check for a record of Engine Stall 2 in the on-board snapshot or the recorded snapshot with the HDS.

    On-board Snapshot

    Select the BATTERY and ENGINE SPEED in the configuration list.

    Pattern Symptom (Diagnosis by parameter) Additional remarks
    Pattern 1 BATTERY voltage low
    GHH428010Courtesy of HONDA, U.S.A., INC.
    • When the BATTERY voltage is excessively low, the PCM or control unit stops functioning, causing engine stall.
    • For PCM or each control unit to start (functioning), more than 7.0 V is needed.
    Pattern 2 BATTERY voltage normal
    GHH428011Courtesy of HONDA, U.S.A., INC.

    Pattern 1 Count is continuously up
    GHH428012Courtesy of HONDA, U.S.A., INC.
    		 When CKP NO PULSE counts go up, the PCM is not receiving the CKP sensor signal.
    Pattern 2 Count is continuously not up
    GHH428013Courtesy of HONDA, U.S.A., INC.

    GHH428016Courtesy of HONDA, U.S.A., INC.
    		 If the FUEL PRESSURE CONVERTED FROM PF SENSOR drops to almost 0 kPa before engine stall, the engine stall may be caused by low fuel pressure.
    • Fuel leak, out of fuel
    • Fuel rail pressure sensor failure
    • Spill valve stuck off
    • Fuel pressure regulator (low pressure side)
    • Fuel pump (low pressure side)
    • High pressure fuel pump

    GHH428017Courtesy of HONDA, U.S.A., INC.
    		 If the FUEL PRESSURE CONVERTED FROM PF SENSOR is nearly the same as the FUEL PRESSURE DIRECT INJECTION SYSTEM when engine stalls, the fuel pressure is normal.

    Which pattern is indicated?

    Pattern 1

    Go to the troubleshooting for DTC P0087 .

    Pattern 2

    Go to step 12 (diagnosis by parameter (AF FB (ST FUEL TRIM))).

  12. On-board snapshot check (AF FB (ST FUEL TRIM)):

    NOTE:  Use the on-board snapshot in the case of an intermittent failure, or use the snapshot in the case of a reproducible failure.

    Pattern 2 Normal when the engine stalls when AF FB (ST FUEL TRIM) is around 1.0 (center value)
    GHH428019Courtesy of HONDA, U.S.A., INC.
    		 The fuel trim is normal when the engine stalled with AF FB (ST FUEL TRIM) around 1.0 (center value).
    Pattern 3 Engine stalls when AF FB (ST FUEL TRIM) is around 0.8
    GHH428020Courtesy of HONDA, U.S.A., INC.
    		 When the value of AF FB (ST FUEL TRIM) is around 0.8, the PCM commands the EVAP canister purge valve to close (closed when EVAP PC DUTY is 0 %). If the AF FB (ST FUEL TRIM) does not move toward 1.0, the PCS may be leaking.
    Pattern Symptom (Diagnosis by parameter) Additional remarks
    Pattern 4 Normal when the engine stalls with AF FB (ST FUEL TRIM) is around 1.0 (center value)
    GHH428021Courtesy of HONDA, U.S.A., INC.
    		 When the value of AF FB (ST FUEL TRIM) is around 0.8, the PCM commands the EVAP canister purge valve to close (closed when EVAP PC DUTY is 0 %). If the AF FB (ST FUEL TRIM) moves toward 1.0, the PCS is normal (no leaks).

    GHH428022Courtesy of HONDA, U.S.A., INC.
    		 When engine stalls after MISFIRE count increases, the engine stall may be caused by misfire.
    Pattern 2 Normal when engine stalls with MISFIRE count remaining constant
    GHH428023Courtesy of HONDA, U.S.A., INC.
    		 If the MISFIRE count remains steady when the engine stalls, the stall was not caused by misfire.

    Which pattern is indicated?

    Pattern 1

    Diagnostic procedure:

    GHH428024Courtesy of HONDA, U.S.A., INC.
    		 If the engine stall occurs just after the A/C compressor clutch turns on, the stall may be caused by excessive A/C compressor load.
    Pattern 2 Engine stalls during A/C CLUTCH is OFF.
    GHH428025Courtesy of HONDA, U.S.A., INC.
    		 If the engine stall occurs just when the A/C compressor clutch is off, the A/C system is not the cause of the engine stall.

    Which pattern is indicated?

    Pattern 1

    Diagnostic procedure:

    • Check for over-charge A/C refrigerant.
    • Check for charging with the wrong refrigerant.

    1. YES (wet)

      Check the following conditions. If those conditions do not apply, go to step 19.

      • In very cold conditions, multiple very short trips can cause the spark plug to foul. If this is the case, drive the vehicle a longer distance and recheck.
      • Incorrect or poor quality fuel can cause a wet spark plug. Replace the fuel and recheck.

      YES (damaged)

      Replace the damaged spark plugs , determine the cause of the spark plug damage.

      NO 

      Go to step 19.

  19. Determine possible failure area (ignition system, others)

    -1. Turn the vehicle to the OFF (LOCK) mode.

    -2. Fit a spark plug to the ignition coil and ground it to the engine.
