Check Engine Light Codes Discussion

[Mike]

He's in fucking uganda or some shit. My legs aren't that long, and I'm to fat to endure his current climate.

got a p0401 code that keeps coming up. I replaced the egr valve.....no dice, keeps coming back

[Mike]

Never done one on an Accord but, from the Toyota's of worked on sometimes the tubing going to the EGR gets clogged as well as the EGR it self, and cleaning it can clear it up.

[CurrentStatus]

I just replaced the egr valve, but how would I clean the tubing to it?

[Mike]

In the past I used carb cleaner it's probably not the best method though.

I'd probably use compressed air.

P2646 - Oil Pressure Switch Circuit Low Voltage

It's #12 in the picture.  There are a few steps that you need to take to determine that it's not functioning, but it's most likely the switch that needs to be replaced.  I have a few of them, but all my spare engine parts are packed away for my move.  You can probably get a complete VTEC solenoid assembly on k20a for around $20-30.  You can use one from an Accord, Civic Si, TSX, or RSX with a K series.  They're all pretty much the same.

P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

Is this the sensor on the cat or the other one (i forget if its before or after it)?

P0141 - Secondary Heated Oxygen Sensor (Secondary HO2S (Sensor 2)) Heater Circuit Malfunction

That is the one on your catalytic converter.  Did you clear the code already?  If you already did that, then check fuse 18 in the fuse box under your dash.  If it's blown, replace it.  If that doesn't work, skip all the other steps in the service manual and just replace the sensor.

Code was cleared and came back within 2-3 seconds after starting the car. I'm going to check the fuse. Is that in the driver side fuse box?

[timot_one]

There are only 2 fuse boxes.  One under your dash and one in your engine bay.

I'm supernoob. For some reason I thought there was one in the passenger side.

Thanks again.

thanks for all the info tim...i found out that the problem was caused by being really low on oil i was missing three Qts ..i got  the oil changed and top off and problem has gone away. i think i need to change out the oil pan gasket becuse it looks like oil leak is coming from and i aslo think my motor maybe is also burning alot of it too..ill keep an eye more on the oil from now on thats for sure.. i cleared the code and has not come back..

[timot_one]

Yeah, checking the oil level is the very first step in the Honda service manual.
