NOTE: Read freeze frame data using the hand-held tester or the OBD II scan tool, as freeze frame data records the engine conditions when a malfunction is detected. When trouble shooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, the air-fuel ratio was lean or rich, etc. at the time of the malfunction.

Check valve timing. See appropriate article in ENGINES. Check for loose and jumping teeth in timing chain. If the results are OK, check and replace ECM. To check ECM inputs and outputs, see PIN VOLTAGE CHARTS article. For removal and installation of components, see REMOVAL, OVERHAUL & INSTALLATION - 4-CYLINDER article. If results are not good, adjust valve timing. See appropriate article in ENGINES.
