My daughter's 2000 Accord started giving her problems with the RPM's revving slightly when the check engine light came on. She was driving along the interstate fine when the car would not accelerate. Would only go about 5-10 miles an hour. We just had the distributor changed a couple of months ago. When the car stopped running completely. My son brought the car to Auto Zone and the put it on the scanner and it gave out readings suggesting that the O2 mix was faulty. Any thoughts as to what to do? Change the O2 sensor first?

 

I moved this out to it's own thread because it's not anything like the transmission problems in that thread.

Do you know the error-code number? It's something like P1234. That would mean a lot more to us than the guy's description.

It's likely the O2 sensor should be replaced, but sometimes you would test something before buying parts. Error codes aren't so cut & dried to point to a single part to replace.

 

Will have a scanner put on the car tomorrow evening. I will post the results tomorrow evening afterwards. Would appreciate any help that you can offer.

 

Here's a handful from my list. There's some additional ones if you have the ULEV engine or V-6.

P0131 (1) pri.HO2S low voltage (P0130)
P0132 (1) pri.HO2S high voltage (P0130)
P0133 (61) pri.HO2S slow response
P0134 (41) pri.HO2S heater malfunction
P0135 (41) pri.HO2S heater circuit
P0137 (63) sec.HO2S low voltage (P0136)
P0138 (63) sec.HO2S high voltage (P0136)
P0139 (63) sec.HO2S slow response (P0136)
P0141 (65) sec.HO2S heater circuit
P0171 (45) system too lean (P0170)
P0172 (45) system too rich (P0170)
