My error codes

Post by soretoez »

Hi guys just need a confirmation or correction on these error codes been doing my research but the p14** codes seem to have 2 meanings. I don't have a pp2k yet but I am planning on getting one asap.

P1352: heating relay or glow plugs. Easy can ignore.
P1435: cat temp sensor or additive
P1445: evap purge valve short.
P1446: evap or additive. Believe it's the addi tank
P1442: evap small leak purge or additive. Believe it's the addi tank

Any advice on where to look what too wiggle or tap with a hammer. I think most are just a duff additive tank. Any help will be highly appreciated.

You really need PP2k to be sure, but 99% chance all bar the glowplug one will be additive related.
Trouble with generic codes is they're just that.

It's fairly common for the additive tank wiring to get ripped off, (sometimes the tank as well). MIght be worth a look.

Thanks doggy the tank was there last time I looked i'll check the wiring when I get home.
The tank sounded empty when I tapped it so possible thermister and pump are dead now. I have no idea the last time it was topped up.

I think the fuel additive ECU is tucked up behind the dashboard, on the left side - there are 2 there, one is silver, one is black, not sure which one you need.

If you decide to defap, I can email you a generic map, and all your fault codes will disappear - except the pre/post relay as it's unrelated.

I'll take a look I got a few hours till I gotta go to work. Hopefully just needs the plugs cleaning or a dry solder joint probably gets quite toasty under the dash.

I'll check the connectors under the carpet as well i noticed some water the wrong side off the drivers door yesterday after the rain.
Not sure if it made it to the floor.

The map would be handy thank you, is there any preference to which gallente? they seem to be about £10 - £70. So not really expensive for what they do.

I bought one for £20, the only issue is the poor quality connector for the OBD2 socket....
Pm me your email and I'll send couple of maps over.
