  • Page 15: Dtc Detection Logic And Conditions[Lf]

    ON-BOARD DIAGNOSTIC [LF] 2-drive cycle type • The code for a failed system is stored in the PCM memory in the first drive cycle. If the problem is not found in the second drive cycle, the PCM determines that the system returned to normal or the problem was mistakenly detected, and deletes the pending code when the ignition switch is turned to the ON position in the next drive cycle.
  • Page 16 ON-BOARD DIAGNOSTIC [LF] P0069 Manifold absolute pressure/atmospheric pressure correlation • PCM monitors differences between intake manifold vacuum and atmospheric pressure. If the difference is below –12 kPa {–90 mmHg, –3.5 inHg} or above 12 kPa {90 mmHg, 3.5 inHg} when the following conditions are met, the PCM determines that there is a MAP sensor performance problem.
  • Page 17 ON-BOARD DIAGNOSTIC [LF] P0126 Coolant thermostat stuck open • If the ECT signal never exceeds 71 °C {160 °F} after engine start for specified period, PCM determines that the coolant thermostat is stuck open. MONITORING CONDITIONS — IAT: above –10 °C {14 °F} —...

  • Page 19 ON-BOARD DIAGNOSTIC [LF] P0335 CKP sensor circuit problem • If the PCM does not receive the input voltage from the CKP sensor for 4.2 s while the MAF is 1.95 g/s {0.25 lb/ min.} or above, the PCM determines that the CKP sensor circuit has a malfunction. •...
  • Page 20 ON-BOARD DIAGNOSTIC [LF] P0455 Evaporative emission control system leak detected (gross leak) • PCM measures the pump load current (EVAP line pressure) when the specified period has passed after EVAP system is sealed when monitoring conditions are met. If the load does not reach the reference current value within the specified period, PCM determines that the EVAP system has gross leak.
  • Page 21 ON-BOARD DIAGNOSTIC [LF] P0500 VSS circuit problem With ABS/DSC • If an error in the wheel speed signal from the ABS/DSC HU/CM is detected by CAN when the following conditions are met: — Neutral switch and clutch pedal position switch are OFF —...
  • Page 22 ON-BOARD DIAGNOSTIC [LF] P0661 Variable intake air solenoid valve circuit low input • The PCM monitors the variable intake air solenoid valve control signal. If the PCM turns variable intake air solenoid valve off but voltage at PCM terminal still remains low, the PCM determines that variable intake air solenoid valve circuit has malfunction.
  • Page 23 ON-BOARD DIAGNOSTIC [LF] P2123 APP sensor No.1 circuit high input • The PCM monitors the input voltage from APP sensor No.1 when the engine is running. If the input voltage is above 4.8 V, the PCM determines that the APP sensor No.1 circuit input voltage is high. P2127 APP sensor No.2 circuit low input •...
  • Page 24: Koeo/Koer Self-Test[Lf]

    • The KOEO self-test is a powertrain control system self-diagnosis, performed when the ignition switch is turned to the ON position and the engine is stopped. A KOEO self-test begins when the connected Mazda Modular Diagnostic System (M-MDS) sends an execute command to the PCM.
