'96 Honda Accord EX, Costly EGR Code
Q: I have a ‘96 Honda Accord EX, 2.2 VTEC engine with 130k miles. The Check Engine light just came on. The code is for the EGR valve. I suspect it is just carbon. However, I was wondering what short/long term problems might I run into if I do not replace the part? It is quite expensive. A: I would suggest not jumping to the conclusion that just because you have an EGR related code that the valve is the fault. Carbon deposits can be removed/cleaned from the EGR valve if that’s the problem. There are problems with the EGR system passages becoming restricted but a new valve won’t fix that, they need to be cleaned. There are also vacuum hoses that are known for breaking, along with a lift sensor, control solenoid and a vacuum control valve as well. An inoperative EGR valve does increase the amount of exhaust pollutants that are emitted. Unbelievably, an inoperative EGR system on your vehicle will also reduce gas mileage. A little time invested checking and inspecting the EGR system could provide a new return.
