Esteem (1.6L)

  1. Perform engine system check. See A4: ENGINE SYSTEM CHECK under SYSTEMS TESTS in SELF DIAGNOSTICS - ESTEEM 1.6L article.
  2. Check spark plugs for proper application, electrode wear, carbon deposits or insulator damage. If problem is found, replace as necessary. If spark plugs are okay, check spark. See SPARK TEST  under IGNITION TESTS in BASIC DIAGNOSTIC PROCEDURES article. If spark plugs and spark are okay, go to step  11. If spark plugs and spark do not test okay, go to next step.
  3. If any DTCs were retrieved during engine system check, perform appropriate test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS in SELF DIAGNOSTICS SELF DIAGNOSTICS - ESTEEM 1.6L article. If no DTCs were retrieved, go to next step.
  4. Check for poor, loose, corroded or damage to ignition coil connectors. Also, check high tension cables. If problem is found, repair or replace as necessary. If no problem is found, go to next step.
  5. Check resistance in ignition cables. Resistance should be 1.2-3.0 k/ohms per foot. If resistance is as specified, go to next step. If resistance is not as specified, replace ignition cables.
  6. Check for open or short in ignition coil power and ground circuits. See Fig 1. If no problem is found, go to next step. If problem is found, repair or replace as necessary.
  7. Check ignition coil and ignitor assembly operation. See IGNITION COIL ASSEMBLY under IGNITION SYSTEM in SYSTEM & COMPONENT TESTING article. If no problem is ground, go to next step. If problem is found, replace ignition coil assembly.
  8. Check Crankshaft Position (CKP) sensor operation. See DTC P0335: CRANKSHAFT POSITION SENSOR - CIRCUIT MALFUNCTION under DIAGNOSTIC TESTS in SELF DIAGNOSTICS - ESTEEM 1.6L article. If no problem is found, go to next step. If problem is found, repair or replace CKP sensor or crankshaft timing belt pulley.
  9. Check for open or short in ignition trigger signal circuits. See Fig 1. Also, check for poor terminal connection. If no problem is found, go to next step. If problem is found, repair or replace as necessary.
  10. Substitute a known-good ignition coil assembly. Repeat step  2. If test result is okay, go to next step. If test result is not okay, substitute ECM with known good unit and retest system.
  11. Check ignition timing and timing advance. See IGNITION TIMING in ON-VEHICLE ADJUSTMENTS article. If timing and timing advance test okay, testing is complete. If timing and advance are not as specified, check timing belt installation, CKP sensor input signals related to ignition system. If problem is found, repair or replace as necessary.
