I put in my vehicle info, and that site didn't come up with any NTK/NGK sensors, just Walker, Denso and Delphi. Hmm. That site has free shipping in the US; I'm in Canada. They will undoubtedly slap on at least 15 bucks for shipping here, if they even ship here at all. Plus, by the time the item arrives, I will waste at least another $20 in excess fuel consumpion! On a tank, it goes less than 400 km, whereas it should be closer to 600. Better idea: yesterday afternoon I went to Vancouver Auto Parts and got a made-in-Japan NTK sensor for $78 + tax, and installed it right away. Now it drives better, and the smell of unburned fuel in the exhaust is gone. Haven't seen any rough idling or power dropout. I will wait for the MIL to go off after a few drives. If not I will reset the codes and see whether they reappear.

It is the "Temporary DTC" for both P0171 and P0172. This according to the FSM for the '00 Acura TL.

The TSB specifically says: "This is a list of all DTCs for all OBD II models. No one model has all these DTCs." P0170 is NOT listed. Can you give some details on the "Temporary DTC" thing? -- Tegger |
