Hello, I inherited a 2000 Honda Odyssey 3

  • 126,000 MILES

Hello, I inherited a 2000 Honda Odyssey 3.8 Liter engine and after driving it the engine check light came on. Used a code reader, and here is the information:

P0420 Catalyst Efficiency Below Threshold (Bank 1)

Parameter Description Results
DTC for which Freeze Frame was Stored P0420
Fuel System 1 Status Closed Loop
Fuel System 2 Status Not Supported
Calculated LOAD Value 50.98 %
Engine Coolant Temp 181.40 °F
Short Term Fuel Trim - Bank 1 1.56 %
Long Term Fuel Trim - Bank 1 9.38 %
Intake Manifold Absolute Pressure 15.40 inHg
Engine RPM 2,037.25 rpm
Vehicle Speed Sensor 68.35 mph
Intake Air Temperature 68.00 °F
Absolute Throttle Position 19.22 %

From this information is it possible to tell me if it will require replacing oxygen sensors, catalytic converter or some other fix please, and a shop time and repair cost also please. It is up for a smog check in a month, and i'm hoping to fix it myself since i'm caregiving full time for several terminally ill family members. Any help you could give me is greatly appreciated. Thank you.

The cat has failed and must be replaced. It is about a 1 hour job plus the part. The dealer cat is about 600. If you use a cheaper one, be prepared to replace it again very shortly.
