DTC P013A:00 [MZI-3.7]: Notes

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

DETECTION CONDITION & POSSIBLE CAUSE

DTC P013A:00	HO2S (RH) slow response-rich to lean
DETECTION CONDITION	During a deceleration fuel shut-off event, the PCM monitors how quickly the HO2S (RH) switches 1 from rich to lean The measured rate of the rich to lean switch is compared to a calibrated error threshold value The threshold value takes into account the level of oxygen in the catalyst, which has an impact on how quickly the rich to lean switch occurs The test fails if the measured value is slower than the threshold value
POSSIBLE CAUSE	Exhaust leaks before or near the HO2S (RH) HO2S (RH) malfunction
