KOER Testing

Ensure engine is at normal operating temperature. Activate KOER SELF-TEST and run engine at 2000 RPM for 5 minutes. This allows the EGO sensor to warm up. DO NOT  shut engine off. System is now in KOER "Wiggle" Test Mode. Tap, wiggle or move any suspected sensor or harness. If the fault can be duplicated, a service code will be stored in memory and will be indicated by the testing monitor. Record all codes and refer to the SERVICE CODE TO CIRCUIT TEST REFERENCE CHART.
