I put my uppipe in at 4k miles and only now has the P0546 CEL come up at 23k miles. You may not have it now, but it will come up eventually.pityr said:Ive had my gutted uppipe on my car for close to 3000 miles and have gotten no CEL yet.
The resistor goes in the female end of the connector. It's the 3rd one down under the plastic coverplate in front of the passenger front strut. If you're doing the uppipe install, you could just get a 12x1.25 bolt IIRC to plug the hole and just pop the resistor in the open connector. Make sure to use some electrical tape to cover and seal the resistor in to the connector to keep it from popping out and away from the elements.Bask Oner said:Check out what cnk has to say. The people who say that an up-pipe won't throw a CEL probably just didn't wait long enough.
So Calvin, the resistor is on the actual sensor in the up-pipe, or on the wire that goes to the sensor (from some harness I assume)? Since I haven't installed my up-pipe yet, should I just throw a bolt in the hole?
I tried doing that, but apparently once you get it, it comes back rather quickly. I have an OBD-II scanner and reset my ECU 3 times before giving up and just doing the resistor mod. Besides, everytime you reset your ECU, you have to put up with crappy performance until the ECU relearns.WRXG0blin said:Well, couldn't you just resert the ecu every......10k miles, im sure its not a problem
