Intermittent Problem Check

WARNING: This page is about a different car, the 2003 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: By putting the vehicle's engine control module (ECM) in the check mode, the 1 trip detection logic is possible instead of the 2 trip detection logic and the sensitivity to detect open circuits is increased. This makes it easier to detect intermittent problems.
  1. Clear the DTC. See CLEARING DIAGNOSTIC TROUBLE CODES .
  2. Set the check mode. See CHECK MODE CODE RETRIEVAL (HAND-HELD TESTER ONLY)  under RETRIEVING DIAGNOSTIC TROUBLE CODES.
  3. Simulate the conditions of the malfunction described by customer.
  4. Check the connector and terminal.
  5. Wiggle the harness and connector.
