Hey guys,

The check engine light on my dash is really bothering me, and when I checked the ecu, it gave me error code no. P1218 and P1413

I couldn't find much online so I wish that you guys can help me.

The mechanic claims that the below adapter is the issue but he didn't explain it well and to be honest I don't know the name of that part

Please help guys.

Thanks

 

My car is an AP1, 2001 Model bone stock apart from CAI and catback

 

I'll look up the codes later if someone doesn't beat me to it.

In the mean time:

1. Not sure what part you mean in the picture. Can you add an arrow or circle to indicate which? An electrical connector is center in the picture, but nothing I'd call an adapter.

2. Regardless that belt at 11:00 from the connector doesn't good. Frayed spot at the the start of a separation line. The threads hanging on or near the tubing beneath the air intake may coming off the belt.

 

Thanks for the reply,indeed the belt is in a bad shape,gonna replace it as soon as possible, any aftermarket belt recommended?

Here's a picture with an arrow: http://s7.postimg.org/k181pr1gb/20151227_063351.jpg

 

No idea on the codes, or even the part. But maybe you should double check the wiring. All that electrical tape wrapping might indicate a less than perfect splice.

 

I have a 2000 model. As far as I know there are no engine differences between 2000 and 2001 models. I don't know whether there are regional variations between our cars for the question here, so for the moment I'll assume there are not.

I have the Honda Service Manual for year 2000 S2000 that was available for customer purchase in 2000. (Dealers surely have more, as well as factory test equipment.) I also have a generic (Craftsman brand) OBD2 Scanner (not a Honda factory diagnostic unit.)

Codes:
My printed manual does not list either code.
My scanner has a built in code library. Looking there, Honda P1218 says "undefined code." Honda has a P1413 code (this means it is a good code for some model and year Honda from about 1995 to today.) This code definition is related to what the sensor you circled could be (see below). The code is for low voltage reading at air control valve solenoid.

You mention having a CAI, which I took to mean Cold Air Intake. But in the picture I don't see a CAI. I see a the corner of a factory Air Box, and a factory intake "hose" (with ribbing). I'm assuming that the air intake is in fact the original factory type.

The Air Control Valve Solenoid should be mounted on the end of the Air Box on the flange that is just toward the bottom of the picture from the corner of the air box in the photo. In your picture no valve there, and there appears to be a broken off piece of something still in the mount flange.

The piece you circled could be the Air Control Solenoid Valve. If it is just lying there, surely yes. If it is mounted there I don't know to what or why. I can speculate that it was to get it out of the way of a CAI that is no longer there. The solenoid should have two wires and two hoses as this one does. I suspect the two hoses connected to it are the same ones in the photo that run diagonally under the wires and that they make a u-turn under the air box. The wiring to this presumed solenoid has an "amateur" looking modification. (Which, assuming the P1413 code is worth anything, could be a source of a voltage problem.)

The metal tube to which the two vac hoses attach has been bent from its original position. It should run above the belt straight toward the bottom of the photo, with the end where the vac hoses attach well beyond the belt and about half way between the air intake hose and the airbox, not jammed between the intake hose and belt.

Are the vac hoses rubbing on the belt?

The connection into the air intake hose at the top right of the photo is poorly fitted. Leaks are bad.

The wire across the top right corner also looks modified.

You appear to have a mix of factory air box and factory intake hose plus modification to solenoid and vac hose routing made for uncertain reasons. I recommend you stay with the factory air box and intake hose. Just upgrade the filter element if you want. Get everything associated with the factory air intake system back where it is supposed to be and checked everything in it for function. Check the wiring, electrical connectors, vac hose condition and their fit. Look carefully for air leaks, cracks - especially in plastic connectors, bad gaskets. Check the solenoid, both electrical and vacuum. Be suspicious of anything that has been modified or disassembled and re assembled. For cheap stuff like vac hose, just replace with new. A hose failing from age after 15 years would not be a rare event.

Look around the intake system area, because there are probably more modifications.

 

It's an accessory drive belt, not involved with engine timing. But losing alternator, AC compressor etc. operation is inconvenient. Around here any decent auto parts store could get an acceptable quality replacement. Or order online from Majestic Honda or probably RockAuto. At your location, I have no idea.

Correct installation and tensioning of the belt is important. Follow the specified procedure. That procedure is probably listed elsewhere on this forum.

 

Thanks Gregg Lee for the detailed answer,the whole engine was replaced and yes I do have K&N FIPK CAI which was installed after taking the picture.

I will be looking for bad wiring or leaks, most probably the issue is incorrect fitment of vacuum hoses. Anyways, I will do a Comprehensive check.

Thanks again.
