So I'm getting codes again. Just got back from autozone:

P0128 - Coolant Temp

P4022 - main catalyst efficiency for bank 1

Now I keep reading that the 2001 V70 has problems with the injectors and it throws catalytic converter codes.... Is P4022 a cat code? Also, I couldn't find anything conclusive on this.

I also read that one code can lead to another, but I don't know which one it threw first!

Thinking about just resetting the codes..... any pointers on this?

 

Yes that is the codes for the injectors.
The coolant temp sensor might be bad making it run rich causing that code as well.

 

So is there any way to determine which injectors are bad or is the name of this game "replace all the dang injectors" ?

 

Sorry but you will need to replace all of them.
I don't think it is really just one that is bad I think it is a calibration problem with all of them.

 

Are you sure the code wasn't P0402? I had the same issue you are having a few weeks ago and I replaced the coolant thermostat. That solved the problem.

I had the coolant temp but my catalyst code read "Catalyst below efficiency threshold" or something similar to what you have, but I believe the code was P0402.

Is your engine temp running at mid-way on the gauge all the time? Tech recommended I replace it to try to solve it the easy way and it worked, but he's the expert. I'm just telling you what I did.

My temp was always running cold, especially now in the winter. I'd be lucky if it stayed 1/4 way up. Once I replaced the thermostat, it was running at normal temps, probably for the first time since I had it, and even in Zero degree weather, the temp gauge stays at half-way.

 

Hm, I'm pretty sure that's the code it threw, at least thats the printout he gave me.

Injectors.... sounds fun. Any recomendations on where to buy? May as well do a thermostat while I'm at it, that is the other code it threw.

 

I haven't done much searching. Not sure of anyone else but the Dealer sells them.

 

Found'em:

117 bucks a pop..... $585 later..... hmm this should be good.

At least the thermostat is only 17 dollars hahaha

 

Why dont you get them rebuilt? I cant remember the place that did mine.
It should be cheaper than buyingnew ones.

 

Check here I know someone that was going to get a set for a S70 for like $250.00 for the 5.
You might want to call them the site looks like just to look through.

Thanks tech for the link. Prices look pretty good.I might check them out whenI upgrademy fuel system

 

If you upgrade alot then go for RX7 older ones.

 

Ok. Thanks

 

Thanks tech - that is good info.

While we're at it, do you happen to have anything you would recommend reading about the injector problem?

 

No sorry I don't.

 

This is from a 700/900 FAQ but it should apply tomost injector diagnosis.

Hmm.... Maybe this one is outta my hands. Might have to just drop it off somewhere. To the think tank i go !!!!
