Hi Folks, following my recent Timing Chain endeavor, I'm getting the following code which returns immediately after it's been cleared:

"P0232-24 (28) Fuel pump A - secondary circuit high - General signal failure - signal stays high"

But unlike others, the truck runs absolutely fine, I've not broken down like @MellonRover described here:


In the timing chain thread here:


@Rover Range had me check fuse F1 (25A) which was fine... I'm wondering if I'm running in to electrical issues, perhaps a failing battery? FWIW, I just measured the battery voltage at lunch time and it's very low at 11.8V but the temperature is also 24F (-5C). I have noticed while driving that the rev counter needle back light has been flickering but other than this the car seems completely normal. I see the voltage generally at about 14.7V when it's running. Any thoughts?

Thanks.

As you know…. Insufficient voltage and current leads to inactivated modules…. It is pinpoint test #1, for a reason…
Your generator is trying but it all goes through the battery…

So you reckon to look at the battery first? It starts really well and runs really well... (esp. with the shiny new timing chains :) )

The flickering needle illumination is something that happens with age, something with the contacts in the instrument cluster itself from what I've researched. I had it before/after my battery replacement.

Thanks for confirming this, did you ever fix the issue? I find it quite annoying but given the low temperatures won't be looking at the moment!

Folks - You are geniuses :).

Battery failed the test at AutoZone (it was dated 10/2019 so not too bad of a run):

A new one is $244.99, based on other reviews I went to Costco and bought an H7 Interstate AGM battery (currently it's $179.99); I installed it this evening and the engine fault is gone :) (Yay). I reset the battery with the Gap tool using this procedure:

Run the routine... Shiny new battery is behaving and comes with a three year warranty. Thanks for the help.

With regards the H8 - I did read that when doing my battery research and took a look while in Costco but to be honest I didn't really want to deal with it on a cold winters evening and don't really need the extra capacity so I decided to skip this for now. I'm just happy to have the fault go away. Thanks. Any thoughts on fixing the flashing needle?

Shiny battery and shiny chains!?
You’re living the high life;-)

Glad its sorted. Lesson learned, don’t underestimate the importance of a sound battery with all systems, even if the engine is running.
