Diagnostic Procedure

WARNING: This page is about a different car, the 2000 Isuzu VehiCROSS, 2000 Isuzu Trooper, 2000 Isuzu Rodeo, 2000 Isuzu Amigo, and 2000 Honda Passport. However, it is still accessible from the selected car via links, so may be relevant.
  1. Perform On-Board (OBD) System Check. Read and record FREEZE FRAME and/or FAIL RECORDS data for each DTC set. Go to next step.
  2. Attempt to start engine. If engine starts, go to next step. If engine does not start, see ENGINE CRANKS BUT WONT RUN under NO START DIAGNOSIS in BASIC DIAGNOSTIC PROCEDURES article.
  3. Using scan tool, clear DTCs. Start and run engine for one minute and observe scan tool display. If any DTC from P0201 to P0206 resets, go to step  5. If no DTC resets, go to next step.
  4. With ignition on and engine off, use scan tool to read FREEZE FRAME DATA and note parameters. Start engine and operate vehicle within FREEZE FRAME conditions as noted. If any DTC from P0201 to P0206 resets, go to next step. If no DTC resets, check for an intermittent problem. See DIAGNOSTIC AIDS .
  5. Turn engine off. Disconnect appropriate injector harness connector related to DTC. Connect an injector tester (noid-light) to injector harness connector. Disable secondary ignition system to prevent engine from starting and crank engine. If noid-light blinks, see INJECTOR COIL TEST in SYSTEM & COMPONENT TESTING article. If noid-light does not blink, go to next step.
  6. If noid-light was on steady in previous step, go to next step. If noid-light did not come on in previous step, go to step  8.
  7. Disconnect PCM connector containing affected injector circuit. Connect test light between battery positive terminal and affected injector driver circuit at PCM harness connector. If test light comes on, repair short to ground in injector driver circuit. If test light does not come on, replace and reprogram PCM. See PROGRAMMING . Retest system.
  8. Disconnect injector test connector. Using an ohmmeter connected to ignition feed wire of injector test connector, probe wire for affected cylinder. If continuity is present, go to next step. If continuity is not present, repair open circuit in injector harness wire or replace faulty fuel injector. Retest system.
  9. At PCM side of injector harness connector, check for short to voltage in affected cylinder wire. If short to voltage exists, repair short in affected cylinder injector wire. Retest system. If short to voltage does not exist, go to next step.
  10. Check for open circuit in affected cylinder wire between PCM and injector test connector. Repair as necessary. If wires are okay, replace and reprogram PCM. See PROGRAMMING . Retest system.
