Went to AutoZone and the reader said 'P0133, bank one of one, slow reaction time'. Only one code. This is regarding the oxygen sensor just past the pre-cat on the front manifold, correct? Is the Oxygen sensor bad or is there something else causing this? Just wonder if this code is masking another problem. Thanx guys/gals! BTW, it is the V6! Last edited by jocatz; 03/30/03 10:05 PM.

Possible causes... -- Contaminated HO2S. -- Exhaust leaks. -- Shorted/open wires. -- Improper fueling. -- MAF sensor. -- Deteriorating HO2S. -- Air leaks. I would say that your "upstream" (before precat) 02 sensor is shot or on its way out. You might be able to clean it, but I would go ahead and change it. As for why this as happened... Investigate the following items as potential sources of HO2S contamination: -- Use of unapproved silicon sealers. -- Fuel contaminated by silicon additives. -- Excessive oil burning (i.e. rings, valve seals and oil overfill). -- Glycol (antifreeze) leaking internally in the engine. -- Lead contaminated fuel. -- Use of unapproved cleaning agents. If none of this is the case, then check for vaccum leaks, exhaust leaks (pretty obvious if you had that!) and check the hose that connects the PCV valve to the throttle body for vaccum leaks as well. All this aside though, I would still bet that it is just one of your upstream 02 sensors. I am not sure which one it would be. I think it is bank 1, but I am not sure. I will let someone else handle that part. Hope this helps. (I love this dang CD!!!) Phillip Jackson `98 Mystique LS 262K+ and counting...

So you need to change Bank 1 upstream located right under the coil pack. just wanted to clear that one up... Phillip Jackson `98 Mystique LS 262K+ and counting...

How many O2 sensors does my car have, it's a '99 with a build date of 9/98? How big of a PITA is it to get to that sensor back there? Any help/suggestions would be much appreciated!

Thanx again guys/gals! Yes! That is the one. I have not changed this one myself, but from looking... It should not be too hard if you remove the coil pack. Duratec has 4 02 sensors. One before the each precat and one after each precat. Precats are located inside the exhaust manifolds, of course. Phillip Jackson `98 Mystique LS 262K+ and counting...

Seems like a good time to change the plugs and wires too! The engine has 70k miles and the only thing I've had to do was change the water pump; I only did that as a precautionary measure. Looking on the NAPA and Parts America web sites and it looks like after 1/2/99 Ford changed something with the O2 sensors. With my luck, they probably made it simpler ! Again, thanks for your help!

With my luck, they probably made it simpler ! Again, thanks for your help! Here is some info that will help clear this up for ya! Bear in mind that the numbers listed are Bosch part numbers... Originally posted by Roz_1999_SVT: the reason the auto store list 2 is becasue up to a certain year, the duratechs used a certain sensor. In 1999 they changed the sensor. So some SVT's had one sensor and some had another. But the sensor befor the Pre-Cat's always remains the same. I have the Bosch Numbers for you to reference. production date: up to 1/2/99 before pre-cat part # 13115 after pre cat #13133 production date: 1/2/99 and on before Pre cat part # 13115 after precat # 13201 As you can see that the only one that changes on the spacific date is the ones after the cats. Bank 1 is the Pre-cat next to the fire wall Bank 2 is the cat in front. I hope you can use the info I provided. Remember these are Bosch part numbers...I don;t have a cross referance for OE.
