I have a 94 Accord and the check engine light is on but also has a very bad smell coming out of the engine when the light came on. I'm afraid to drive it right now. What is the best course of action to take? Please help!

 

Read the codes from the ECU and trouble shoot accordingly.

Self diagnosis is done the same way as on the Civic's & Teg's. I have done it more than a few times myself. There is a blue 2pin/wire connector attached under your glove box/side of the passenger footwell. That is the one that you short to do the SCS self diagnostics.

This is the procedure I used for my 96 Accord.


Here is the blue plastic retainer that is connected to the chassis. The connector is sitting inside this plastic retainer/bracket. (may not be the exact bracket on the 94-95)


This is the two pin connector removed from the retainer. Showing the two female pins where you are to stick the ends of the paper clip or wire.

 

Thanks for the advice. It came up with a code of 41. How can I find out what that code means?

 

code 41 is the primary 02 sensor, what engine do you have? that sensor is located on the exhaust before the cat

 

I have the F22b. DOHC VTEC!

 

Thank you both for your help!

 

a bad o2 would make your car smell like rotten eggs or at least an unpleasent smell.
