Engine Performance problem
1996 Chrysler Town and Country 6 cyl Front Wheel Drive Automatic 164751 miles
My 1996 Chrysler Town & Country 3.3L failed the smog test with more than double the allowable amounts for a gross polluter. The only OBDC code is P0140 which is "oxygen sensor ckt inactive (bank 1, sensor 2)". I replaced the oxygen sensor upstream of the catalytic converter but the code is still reading the same. Is that the code for the sensor downstream of the catalytic converter or the one upstream of it? The smog test technician seems to think that the problem is more likely due to a failed catalytic converter rather than just the oxygen sensor because of the extremely high readings of pollutants. What should I do?
have the same problem?
