Item | Detecting Condition | Possible Cause |
DTC Strategy | ● Comparison of HO2S switching time with calculated switching time | ● Contact resistance in connectors ● Open or short circuit ● Malfunctioning HO2S |
Enable Conditions | ● Mass air flow <250 mg/stk ● No misfire detected ● Not transient condition | |
Threshold Value | ● Sum of HO2S switching time 〉Calculated switching time | |
Diagnostic Time | ● 80 lambda controller cycles |
