General Smog Check
 

2006 Honda Odyssey O2 Sensor Circuit No Activity Detected

I have two trouble codes on my Honda Odyssey: P0154: O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 1), and P2254: O2 Sensor Negative Current Control Circuit Open (Bank 2 Sensor 1). Can my Odysses still pass the California smog test with these codes being present but the check engine light not being ON?


Answer:  

Passing the smog inspection in this scenario will completely depend on whether your Honda Odyssey has completed its emission monitor tests. Emission monitors are internal self-tests which the ECU (engine control unit) performs in order to ensure all emission systems are functioning properly. When a problem which causes the check engine light (CEL) to illuminate is presented, the emission monitor pertaining to the emission system presenting a fault is unset. The emission monitor (in this case: Catalyst Monitor) may also not be complete or ready for the smog check even with the check engine light off. The fact that the two trouble codes you mentioned (P0154 and P2254) were at some point triggered (set as pending and not hard), may have very well caused the Catalyst Monitor to remain "Incomplete". If this is the case, your Odyssey will not be able to pass the smog test; even with the CEL being off. The best way to find out is to use a OBD Scan Tool to verify all the monitor status.

To answer your question in short, should all the monitors be completed (except for the EVAP monitor, which is the only incomplete monitor allowed as of the time of this post), and the check engine light not be on, your Honda Odyssey can pass the smog test.
