DTC DETECTION LOGIC AND CONDITIONS [MZR 1.3, MZR 1.5]

id0102f8100300

• The DTC detection conditions which have been added to vehicles with the gear shift indicator are as follows:

P0069:00 Manifold absolute pressure/atmospheric pressure correlation

• The PCM monitors difference 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 or BARO sensor performance problem.

MONITORING CONDITIONS

― 12—15 s from when ignition is switched to off

P0401:00 EGR flow insufficient detected

• The PCM monitors the difference in the intake manifold pressures when the EGR is operated and when it is stopped. If the difference is too small, the PCM determines that the EGR flow insufficient.

P2228:00 BARO sensor circuit low input

• The PCM monitors input voltage from the BARO sensor. If the input voltage is below 1.97 V for 5 s, the PCM determines that the BARO sensor circuit has a malfunction.

P2229:00 BARO sensor circuit high input

• The PCM monitors input voltage from the BARO sensor. If the input voltage is above 4.0 V for 5 s, the PCM determines that the BARO sensor circuit has a malfunction.
