What sensor is it? I assume it's the 02 sensor but is it upstream or downstream?I have had my 05 wrx for 3 months and this is the second time the exhaust sensor has burned out causing the check engine light to come on.. Now i have a 3 hr. drive to get it fixed. does anyone know why this sensor keeps burning up. HELP!!:sadwave:
yeah i will try to get a picture of it.. i got the code of what the comp. says and it says that the "Exhaust gas temp" is high... Thats the same thing that it said before when i first bought it.. now the first time this happened, subaru reset the comp. and obviously the light came back on because all the did was reset the light until the new sensor came in... "it had to be ordered".. anyways.. this time i checked the code with a scanner i bought and i dont think the light gets reset cause it was on after i checked it... anyways i drove for about five miles and the light went off. and now after restarting the car a couple times the check engine light stays off...
Well most people do not just toss on a STI intercooler as the only mod. When you say exhaust is it a turbo back exhaust. Most people when they do exhaust they will change out the uppipe since it has a cat before the turbo.No... no catless up-pipe. the everything is 99% stock.. the guy before me put an sti intercooler and exhaust on.. thats as much as i know, and can tell....... i have a friend who has a subbie and he said that my turbo is really loud. like you can hear it more than in his car. there isnt a bov or anything and its the stock turbo.. just wondering what that could mean if anything.
The Code Is "p0546"
+11I don't know if the OP is still having issues, but I don't think anyone brought up the fact that his ECU could have been re-mapped with something other that the stock programming. If that's the case, the reflashed maps could very well be 93 octane specific and it's no wonder he's seeing abnormally high EGT's while running lower octane fuel.
To jast513, replacing the sensor or doing the resistor mod isn't going to remedy the condition that caused your CEL's in the first place (see preceding paragraph). However, take a look at the UP/exhaust install guide which is stickied in the Engine Performance section of the Tutorial forum. That should give you a better idea of the sensor location.
