on 1996 Honda Del Sol 1.5L I4 · FWD

What this code means

Common causes

  • Faulty IMA motor rotational sensor
  • Damaged sensor wiring/connector
  • Motor control module fault
  • Charging/discharging system issue

Diagnostic steps

  1. Scan for IMA/hybrid codes
  2. Inspect rotational sensor wiring and connectors
  3. Test sensor signal output
  4. Check motor control module operation
