DTC NO. DTC DETECTION CONDITION TROUBLE AREA P015A The "Rich to Lean delay level*" value is less than the standard. (2 trip detection logic) Air fuel ratio sensor (for bank 1 sensor 1) Air fuel ratio sensor (for bank 1 sensor 1) heater ECM P015B The "Lean to Rich delay level*" value is more than the standard. (2 trip detection logic) P015C The "Rich to Lean delay level*" value is less than the standard. (2 trip detection logic) Air fuel ratio sensor (for bank 2 sensor 1) Air fuel ratio sensor (for bank 2 sensor 1) heater ECM P015D The "Lean to Rich delay level*" value is more than the standard. (2 trip detection logic) *: Calculated by the ECM based on the air fuel ratio sensor output MONITOR DESCRIPTION After the engine is warm, the ECM carries out air-fuel ratio feedback control, and maintains the air-fuel ratio at the stoichiometric level. In addition, after all the preconditions have been met, active air-fuel ratio control is carried out for approx. 10 seconds, and during active air-fuel ratio control, the ECM measures the response If the time it takes the air fuel ratio sensor output to change is delayed, DTC P015A, P015B, P015C and P015D are stored. 3UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P014C-P014F... |
