OBDII issues

[pyrotic37]

I put a jumper in the green conn to display any possible error codes. I know that at least on of my o2 sensors are bad, and the maintenance light just stays on (No flash.) Is this an actual error code, or do I have Mad problems?

I'm not quite sure if its a serious problem but you can turn off the maint. light. Just turn the key but don't start up the car and under the dash theres a blue square button press and hold till the light goes off.

What i mean is when i jumper the conn so that any error codes will flash, the maintenance light is just illuminated ( no code flashes) i can turn it off by removing the jumper. Any ideas on whether or not this is infact a code, or is the jumper trick not working?

If the "Jumper Trick" isnt working you can bring it to a shop or HONDA and they can hook up a scanner to see if there are any codes being thrown. Are you sure youre doing it right? And how do you know the o2 sensor is medded up?

How To - check for CEL - the jumper way

Yeah, i am using the correct plug to jumper, and it just doesnt make sense. Everything points to my o2 sensors. I used to get 460 miles to the tank, this was at 45K. Now i am lucky to get 250. I drive the same as always....balls to the wall. any ideas?

I dont think the jumper wire works with OBD II, only OBD I... but I may be wrong. I think you need a scantool.

It does work with OBDII. Are you sure you are jumping it right? Cuz sometimes it won't make contact quite right and the CEL (not maint. light) will just stay on like normal.

460 miles in a tank, huh? That's a good 40mpg, sorry bro but are you sure? That seems pretty damn impossible. 250 miles driving hard is perfectly normal. The most I've ever gotten was 330 in a tank and that was very near empty, with the rear seats and spare stripped out. And I drive quite conservatively usually.
