RE: Error Code A2 4-1-3 EGR Temp Sensor
I just saw the price of that sensor on FCPGrotton... $192. Well that's a chunk haha I'll check for wiring conditions and maybe see if I can try a used one on in there.
What are the results/effects of an EGR system that is not working that great?

RE: Error Code A2 4-1-3 EGR Temp Sensor
Hello Mr. MikeySq,
Greetings from windy Chicagoland.
EGR valve is meant to return a part of exhaust gas back into the intake side. This reduces the combustion temperature and lowers emission byproducts (according to smart engineers). It also gives unburned fuel another chance to get burned.
I think the effects defer from car to car. Some car may stumble or stall, while other cars run fine, except the emissions may be higher than normal and you'll get that annoying "Check Engine" light. Some cars may also suffer drop in fuel economy.
I wonder if there are some effective ways to clean/repair these sensors. They are overpriced, regardless of what sensor (O2 sensors are almost $200 each, and 850s have two of them!).
Good luck,
JPN
