Special Tools Required

Vacuum Pump/Gauge, 0-30 inHg Snap-on YA4000A or equivalent, commercially available

NOTE:

  • Before beginning this troubleshooting, do a customer diagnostic interview - Refer to: Fuel and Emissions Systems Symptom Troubleshooting - Engine stalls Diagnostic interview, or Fuel and Emissions Systems Symptom Troubleshooting - Hard to start engine Diagnostic interview.
  • When the symptom cannot be duplicated, you can do the troubleshooting using the on-board snapshot information in this procedure - Refer to: PGM-FI System Description - OBD, or PGM-FI System Description - On-Board Snapshot. Refer to the diagnostic interview (date, place) and the present total mileage, and compare the total mileage which is estimated from the interview when a failure occured and the parameter (total mileage) in the on-board snapshot information.

    Make sure the date when the failure occured corresponds with the date on which the on-board snapshot information was recorded. If it doesn't, the on-board snapshot information cannot be used in this troubleshooting.

  • Before beginning this troubleshooting:
  • Make sure the 12 volt battery is fully charged.
  • Make sure the fuel tank is at least 1/4 full.
  • Make sure the engine oil level is correct.
  • After the troubleshooting, reset the PCM with the HDS to erase the on-board snapshot information recorded on the PCM.

1. DTC check.

  1. Turn the vehicle to the ON mode.
  2. Check for Pending or Confirmed DTCs with the HDS.

Fuel and Emissions - Testing & Troubleshooting

Are any Pending or Confirmed DTCs indicated?

YES

Go to the indicated DTC's troubleshooting.

NO

Go to step 2.

NOTE: If the HDS does not communicate with the vehicle, go to the PCM power and ground circuit troubleshooting.

2. Immobilizer system check.

  1. Check the immobilizer status log (With keyless access system), (Without keyless access system).

NOTE: When a status log count is found, it means the immobilizer system has kept the engine from starting in the past. The number of status log count shows how often the system has kept the engine from starting in the past. If the immobilizer system has no status log count, the system is normal.

Were any status log counts found?

YES

Check for probable cause of the status log.

NO

Go to step 3.

3. Problem verification (snapshot sampling).

  1. Set the HDS to record a HIGH-SPEED SNAPSHOT of following parameters for 30 seconds.
  • IMMOBILIZER
  • ENGINE SPEED
  • BATTERY
  • ECT SENSOR 1
  • MAP SENSOR
  • MAF SENSOR
  • CMP NO PULSE
  • CMP NOISE
  • CKP NO PULSE
  • CKP NOISE
  • EGR LIFT
  • EGR valve position sensor (EGR VLS)
  • VTEC SOLENOID VALVE (USA and Canada models)
