CEL Issue (Error P1166 & P1167)

[Flippit]

Its weird how you have this problem Phil. You deadset have tried everything. Really unsure of this.

Some tips for people in the future who may run into this problem.

Get an angled defouler. I purchased a straight one, only to find that when screwing this in, in addition to my secondary sensor. I was hitting the chassis. I solved this by cutting 10-20mm from the center and welding the edges together and fixed my problem ever since. Highly reccomend an angled defouler.

Oh and regarding the lack of wiring loom for the secondary sensor. getting the extension is a waste. Honda has left quite some slack if u follow the loom up towards the engine. Its been kept up there with either a cable tie or electrical tape. Just have to cut some away and you have plenty of slack to get the secondary o2 sensor screwed onto the defouler.

When the CEL light is on, it puts it in Limp mode. Lack of power and bad fuel consumption has been experienced so I wouldnt ignore it. Maybe its some signs telling you to get Hondata KPRO, Power and elminate the CEL light.

You sure it goes to limp mode? Car feels to go alright Me thinks?!
Speaking to a mate at honda he reckons sometimes the scanner can't get rid of the CEL light. He 'reckons' try their scanner and it should do the trick? Also said sometimes aftermarket o2 sensors bring up CEL lights also ;\ ?
Anyway heading off to my bro's workshop next week I'll try their scanner see if that does anything.

Kpro too much, no point if I don't drive the car?!

Woudnt have somthing to do with you not driving the car often?? Off fuel ect

Nope, it had the light soon as I put the exhaust on at Toda when it was daily driven. Definately not fuel related or anything.

i've had a CEL issue for quite some while aswell. i'm getting normal fuel consumption.

if i start the car and drive off straight away, it'll stay off until i'm at a set of lights for about a minute or more. if i start it and let it idle for a minute or so, it'll come on. so if i get caught at a few lights it'll come on. if i get a lot of greens then it's off for the whole trip. on and off.
anyone know the problem?!

Thats weird as! You got a defouler/spacer/reducer on it? If not try one and should do the trick as your's only comes on when stationary must meen only get CEL when the flow builds up. You'd think it be other way around?

I think DJ's problem may be different though as he's running stock header + cat. (but he is balling so maybe he has something none of us know about)

what error code do you get when the engine light is on?

Where did you buy the angled defouler?

Ebay seems to be the go, but shipping is killer.

Yeah i got mine off ebay.

Just a thought. The crank case breather might be your issue

[ChargeR]

Flippit you state you have replaced the secondary O2 sensor, added extensions and replaced your extension wiring, but P1166 and P1167 refer to the primary O2 sensor not the secondary. So if the codes you state are correct you have been working on the wrong sensor.

Nope.

ok ill shut up.

ok ill shut up.

No need to take it to heart, but the crankcase ventilation system on a K series has two main parts, the PCV which vents to the intake manifold and the breather on the valve cover, which is connected to the intake. Neither are remotely near the exhaust or are likely to affect the operation of an O2 sensor, the engine would have to be burning massive amounts of oil or crankcase vapours for it to cause issues that far downstream.

Thats what I'm thinking, but it also says on the diagnostic tool Bank 2 which is secondary o2 sensor, and when i asked Adrian at Toda about it he said those codes meen the secondary sensor. So I'm not sure.


edit : I also remember reading or him saying can't remember but the error says Heater sensor which only the secondary sensor is called a "heater sensor".
Maybe ill just buy a primary sensor also to be on safe side.

CEL was up way before putting on the breather.
Plus I personally think that would have nothing to do with it.

Here's an excerpt from the workshop manual. I'd trust that more than the code reader, because while the codes are generic OBD2 I think there is manufacturer variance on what each actually represents. Get the manual, follow the troubleshooting for those codes. Save yourself some money and time .

[Flippit]

Shitballs. Time to buy the other o2 sensor.

Ahwell atleast I have 2 new sensors lol.

[Karl]

Nothing taken to heart.
