The plastic coolant bleeder vault on my '07 LR3 cracked today giving the portions of the engine under the engine cover a health bath of coolant. After that I started to get a MIL with the codes p0201, c3401, p0171 ( See below for details). I am assuming the p0171 is caused by the p0201, but I don't know what c3401 is. What I am wondering is whether once the engine gets thoroughly dried out the code while go away. I have cleared it a few time but it keeps coming back. I know there is still some drying to be had because the foam under the engine cover is still wet.
Any thoughts?
Am I going to have to replace that Injector?
Does any one know what the c3401 code is?
Why would anyone make that coolant bleeder valve out of plastic?
Anyone know where I can get a good replacement for the bleeder valve? I have a brass coupling in there for now.

re: Why would anyone make that coolant bleeder valve out of plastic?

Designed by engineers that never had one break whilst wheeling monster-in-law and SWMBO on a long trip.....

 

Injector 1 is accessible, I would remove and clean the connector to start with.

C3401 is not a valid code in either PCM or TCM, which is all that most generic scanners will read, however, C0034-01 could be stored in the PCM for a fault with the RF wheel speed sensor, and a generic scanner may misinterpret that fault.

 

Could C3401 be the connect that is an issue? I don't have a service manual to look up which connector that is. But they are labeled Cxxxx, right?
