Weirdest issue I'm experiencing. Third time now in a couple of weeks, I've blown the following fuse outlined in red:



The EPC light comes on and there's major loss of power. Turn the car off and back on and now the engine light is solid, EPC off.

Error codes are:

P1195 (Fuel pressure control valve) - hence the loss of power
P3087 (Electrical error in circuit)
P1435 (Secondary air injection (AIR) pump relay).

I know this from my mechanic who replaced the fuse the first time.

Before I go leaving my car with him for a full day to seek out a short with the Fuel valve or sec. air pump, there's another issue I realized. This happens shortly after I get a left rear bad turn signal bulb or front left DRL warning, yet there's no problem with either. Turning the car off and back on clears the issue. Then shortly, within a minute to a few hours, the fuse blows.

I haven't been able to find out exactly what this fuse is (ECU?) but could it be possible that another circuit is causing this one to overload, unrelated to the engine? Anyone got a fuse box (engine compartment) diagram to share with designations for each? Thanks.

have you ever figured this out yet?

Sorry, never saw your reply!

Yes, but no actual reason was given. Mechanic had it all day, testing and probing and couldn't get it to duplicate the issue and haven't seen it since. WEIRD.

The EPC Light comes on and the engine conks into limp mode. Kill the engine start it again no problem I can drive off on my Merry way. But I'm getting all the same warnings about lamps not working or brake lights not working and this is the exact same situation I'm having. Another odd thing I noticed is that the engine fuse layout does not match what's in the 2010 owners manual. The engine fuse layout is the same one this picture here but according to my owner's manual it should be totally different. It's furthermore my main problem now is that the car died the other day and I'm getting 01314-013 ECM DTCodes.

I'm hoping OP could maybe lend some guidance or that anybody could lend some guidance on what the hell's going on here because the car runs fine until this.

also isn't it odd that my car and OP's car here have 2012 through 2016 engine fuse layouts for 2010 models?
