DTC 0136h – O2 Sensor – Downstream.

Fault Type	Description		ABC Type
24h	Signal remains High when Transitions are Expected
23h	Signal remains Low when Transitions are Expected
13h	Circuit Open		Sbx_cf
11h	Circuit Short to Ground		Sbx_cf
12h	Circuit Short to Battery		Sbx_cf
Detection Conditions for Bit 4 (readiness)
24h	The abnormal voltage on the lean side diagnosis is done
23h
13h	[Downstream sensor heating activated almost one time during the current driving cycle (engine running time > 5min at idle speed) AND engine autonomous AND DTC 0141h not present] during 5 s
11h	Engine running AND out of injection cut-off phase AND DTC 0105h, 0095h, 0115h not present
12h	[Engine running AND Accelerator pedal pressed AND DTC 0141h not present AND Downstream sensor heating activated and warmed up after 5min] AND during 5 s
Detection Conditions for Bit 0 (test failed)		Detection timing	Resorption Timing
24h		0 ms	0 ms
23h		0 ms	0 ms
13h	Lambda sensor signal > 1300 mV after more than 10s of injection cutoff	10 s	10 s
11h	Rear Oxygen Sensor signal < 20 mV	< 30s	< 2s
12h	Rear Oxygen Sensor signal > 1870 mV	< 2s	< 2s
