Honda CRV (2000) - Hooverage!

[twosmoke300]

the table was a std fit

[beko1987]

Yep, it has the table! Layby picnics FTW! Also found the toolkit rattling around in the boot door, we removed it to see if it stopped any rattles.

 

It bloody shifts! I struggled to keep up at times, although I bet it rinsed more fuel than I did! 

 

This was him telling me not to put any pictures up on facearse, which I truthfully replied I would not...

 

 

The proud* owner of a lovely* car

 

 

The first drive as the owner

 

 

It blends right in

 

 

He's gone to the post office to tax it as the online system said NO. No pez station shot as it has 1/4 in it, he wants to run that out then brim up and put a bottle of redex in. Rob - they remembered you, asked how it was al lgoing. I said fine as far as I know, and pointed him towards our fine forum!

[gordonbennet]

I reckon he's picked himsen up a little cracker there...^^^ bellends in that well it's bleedin vanished.

Yes, there was a special edition with a shower in the back.  Great cars these, I loved mine, massively useful and dead reliable but my word they do like a drink.

 

 

Skizzer's Rover SD1 has a shower in the front, but it's called the windscreen seal, and his N hers bathtubs, but they are called the gloveboxes.

The fuel economy is the only negative about it so far, and he only does 12 miles a day to work and back so hopefully it's liveable with. The trip computer shows 340 miles down, and the needle is below the 1/4 mark so we are presuming it'll need a drink soon. This will occur with putting all the tyres to the same pressure and fitting an air freshener prior to a damn good hoover out as it's full of soil and grass

[beko1987]

Apparently the eml came back on during a wet drive home (was raining when we saw the car yesterday, then was dry when we turned it off....)

 

Will check the sparkers and ht leads tomorrow lunchtime i think. Presuming its put the same code back om anyway

[gnomeot]

Yep, misfire on cylinder 2 came back on in the rain yesterday. Myself and beko1987 are gonna grease some parts at lunch today and see if we can't give it a temporary fix until next payday.

 

Fuel economy report...filled up yesterday evening. Done 70miles since and used about 1/8th of a tank. I reckon I'll see just over 350 miles out of a tank for £55. Thirsty, but liveable. Everything feeling much smoother after a bit of a drive though!

[beko1987]

 

Stupid large modern cars blah blah

[twosmoke300]

Check valve clearances , very important on these

Honda oe ht leads are very very good quality and should outlive the car

[phil_lihp]

That's interesting, I took mine to my nearest Honda dealer in Exeter to get a new key coded and the chap on the service desk said I should get the valve clearances checked.  I assumed they were just trying to sell me the work, smiled politely and never did check them.  Oops.

[beko1987]

It's had those before, looking at the paperwork, was when it was a bit younger though.

[320touring]

 

 

you need to get that zx painted gold. stat.

Stupid large modern cars blah blah

[beko1987]

There's a touch up stick in the Honda, would be a start.

 

I could mix it with the green stick in the ZX and do some custom pinstriping... Or find an old persons home and steal 5l of OAP beige matt...

[beko1987]

We haz a different eml code! 

 

P0420 - Bank 1 sensor fault, which a quick google shows it could be anything for spark plugs to OMGNEWEXHAUTSYSTEM... - http://www.crvownersclub.com/forums/14-problems-issues/16234-dreaded-pita-p0420-code.html

 

Will leave it for now, have cleared the code, will see what pops back up, and if it's only when damp etc.

 

Unrelated question, if the catalytic convertor was removed, would it pass an MOT, and would nuns and kittens die? (2000 X car). Gnome knows an exhaust chap who would replace the cat with a hollow peice of pipe for £beer money were the cat to be at fault...

[twosmoke300]

P0420 is a cat below efficiency code , either its got a poorly cat or a cheapy aftermarket one . Hondas will always put a light on eventually with cheapy cats . No problem driving it tho as long as it passes mot .

It will fail a legit mot without a cat.

 

Valve clearances need to be done every 27k miles

[twosmoke300]

5 and 8 thou for the clearances comes to mind

[beko1987]

Was thinking cat, if it's the original one it's on 137k...

 

Would a non type approved £50 ebay cat last a few years? Even if it needed a new one every few years surely it's still cheaper than going to Honda?

[twosmoke300]

It will bring the light on , best bet is to leave the original on if it still passes MOT. They usually do.

 

Does it stall or come close to it when you get to the first junction on warm up?

[beko1987]

Nope. At best apparently, when its hot (30-40 minutes), the idle can get ever so slightly lumpy for a second or 2, then back to normal.

 

The plan for now is:

 

Code is cleared now, and it's dry, so drive home/about tonight - check for eml

It's supposed to piss down tomorrow nad friday, so see if the eml comes on at all

New sparkers, ht leads, dizzy module, oil change, fuel filter change

Remove the 02 sensors and give them a clean up, check the connectors for any issues etc

New cat/cheapy cat and hope...

 

MOT isnt until June next year so we have a while to wait to find out if it'll pass the emissions. There was no smoke coming out of it when we drove it home yesterday, and it was pulling away from me at 85 with alarming speed on the m40...

[MarvinsMom]

I approve of the cut of your jib young man!

 

drive it, enjoy it, and worry about it when the test is due (and not before)

[rainagain]

You can also remove the secondary lambda probe and tie wrap it out the way, making sure to screw in a suitable bung to the exhaust. The primary lambda prove is used to control closed loop running. The secondary checks for a lean mixture at all times as the cat has burnt off any HCs. As the cat gets older it cant manage this as well. Leaving the secondary probe out the exhaust completely but still connected stops the poor cat efficiency fault code

[beko1987]

Interesting!

 

If an ignition system overhaul, service (although its a well serviced car, the oil looks very clean), and a clean of the exhaust sensor plugs doesnt do it I think new cheapo lambda sensors are on the cards.

 

Going to see what the weather does to it first, havent heard from Gareth but I presume the light is still off. Need to get my obd scanner working on his phone, then he can borrow it as I dont need it for now. His S6 wouldnt find it earlier when we tried.

 

We did have the leads off one at a time earlier, with a view to seal the rubber to metal joins with grease but they look fine, spotless underneath so put them back. Air filter is very recent, and not in need of changing. Couldnt get the rad cap off to have a look, is there a knack to it?

 

Didnt want to pull the plugs until we have new ones to put in, Gareth is playing the ignorance is bliss card on that one

Not on Hondas it doesn't I'm afraid . On a Honda the ecu looks for the number of zero crosses in a given time period . An oxy sensor ( primary ) swings from 0.1v to 0.9v about once a second as it goes weak/rich . A secondary sensor should remain a reasonably steady 0.5v as the cat keeps it on stoichiometric (sp?) . If the ecu sees the secondary sensor mimicking the primary one it knows the cat isn't doing it's job so pings up p0420 code . If you take the sensor out it will think it's running far too lean and bring a fuel trim code up so you still have the light on . It will prob show a secondary oxy sensor code too .

 

I wouldn't bother with ht leads or the ign module unless you have hot non start issues

Aye, my Accord is at 130k on the original leads with no problems, you very rarely hear of Honda (Denso i believe) HT leads going bad.

I recently fitted this lovely stainless steel manifold to my Punto

[rainagain]

As you can imagine as it didn't have a CAT in it, it brought up the P0420 code. I read on the Fiat forum the advice I gave above about removing the secondary probe and leaving it tie wrapped out of the way. However I could only remove the secondary probe if I removed the manifold due to the lack of clearance as you can see below. As it was such a ball ache to fit I didn't fancy doing it a second time.

[rainagain]

So I did a bit of digging and found this site: http://www.newcelica.org/forums/showthread.php?t=216641

 

I don't like the idea of hacking about the lambda probe wiring so I nipped down the scrappies and chopped of the plug and socket in the lambda wiring. I then made up the low pass circuit suggested in the above website and fitted it to a small piece of veroboard  I then had a nice low pass filter I could insert into the secondary lambda probe wiring 

[rainagain]

I potted the veroboard in epoxy to protect it, taped up the wiring before slipping over some protective sleeving I also nabbed at the scrappies, I then inserted it into the lambda wiring and viola no more P0420  

[rainagain]

An example circuit is shown below, wiring colours will vary.

 

You can also fit spacers to the secondary probe so it is in more 'dead air' so fluctuates less:

Bit off topic but just had a thought. maybe P0420 is a sign from the raffle gods?? Next raffle on here he needs to pick 4 & 20.
