KOEO & KOER Diagnostic Trouble Codes

WARNING: This page is about a different car, the 2002 Ford Pickup and 2002 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

If a DTC is set, it may cause the Malfunction Indicator Light (MIL) to turn on. The MIL is located on instrument cluster and may be labeled SERVICE ENGINE SOON or CHECK ENGINE. KOEO & KOER DTCs indicate faults exist at time of testing. For additional information on KOEO and KOER DTCs, see DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTIC SYSTEM in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article. If KOEO or KOER DTCs are retrieved during KOEO ON-DEMAND SELF-TEST or KOER ON-DEMAND SELF-TEST, see DIAGNOSTIC TROUBLE CODE DEFINITIONS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
