Honda HR-V: Engine Stalls

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 PGMFI 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 occurred and the parameter (total mileage) in the on-board snapshot information.

    Make sure the date when the failure occurred 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?
