Question

I have P2254 and P0154 on 2005 Honda Odyssey, What is the fix

Answer 1

P2254 Front A/F (airflow sensor) bank 2 sensor 1 VS line high voltage

P0154 Front A/F (airflow sensor) bank 2 sensor 1) heater system malfunction

The fix is to repair P2254 first, this can be a malfunction with the air flow sensor, (referred to as oxygen sensor)., or with the harness, not making proper connection to a failed PCM not able to give heater IGN +2 or the PCM heater control(-).Another fix is to subsitute bank 1 sensor 1 heater IGN with a jumper to bank 2 sensor 1, clear code, and  retest by starting the engine and hold engine speed at 3.000 RPM (without load) in park or nuetral.until the radiator fan comes on and let it idle for 2 minutes recheck the code it if returns subsitute this time with bank 1 sensor 1 heater control system.If one of these test fixes the problem the solution is with the PCM.
