Help! CEL trouble codes 301, 302, 303, etc and can't fix
Posted 22 December 2003 - 12:32 PM
I fixed the cold-air issue myself (it was a split vacuum hose). What it god's name could the dealer have done? BTW, avoid Heritage like the plague. Their service department stinks and they were rude to me when I complained about what they had done (and I was a very good customer, having bought or leased 5 or 6 Hondas from them over the past ten years). They've lost me as a customer forever.
suzukatim at Scott Honda (where my tranny was very ably fixed) thought it might be the VAFC making the mixture too lean, so he set all the settings back to stock. No luck -- the codes are still popping up. Before I subject the car to another local Honda dealer (Scott is too far to go for this), anybody have an idea of what might be going on? The procedures in the Helm manual for tracking the problem are quite long, and I thought someone might already have had experience with this problem that might prove helpful.

Misfire DTC's are P0301-P0304. The cheapest and easiest thing to check is a set of spark plugs. I would get a set of non platinum plugs and go from there.
But he said the codes were 401-404. Anyway I think it might be an 02 sensor problem.

Of course, I had about 56k miles at the time. Not sure what your issue could be.:(

I haven't seen that on here begfore...does the honda puter have a clock? They ran my car found nothing wrong and told me it "burped". Unexolainable as to why. Mine went off about 12noon et.
They had just seen another honda that did the same thing. They pulled my plugs, among other things, I don't know if they checked gap or not but they said they checked it all and could find no reason.
What time did you get yours Rick?

I'm pulling the codes with and OBD-II scan tool.
This 300, 301, 302, 303, 304 problem appeared immediately after I had the car to a dealer for a CEL code related to the cold air injection. They didn't fix that and left me with this problem as well. The cold air injection code was triggered by a crack in a vacuum hose. I fixed the hose and that problem has not shown up again. but I appear to be stuck with this one.
