Please direct your solution to NoHaveMSG, because I would have no idea of what you're talken about -

i don't have the solution, but enjoy reading about it!

Well then, you ought to get a real kick out of following these electrons running along side of each other -

I think they get their stuff on the 1st, so should be good.

It is a Sevcon Millipak for a separately exited DC motor, 48V 500a with a Sevcon linear throttle actuator that is decreasing voltage output signal.

Found a manual. Seems pretty straightforward.

My CEL just flashed again and I got two codes on my diagnostic tool: P0303 and Acon B14A1. I don’t know what to do at this point. Decided to just post this instead of messaging.

Yes, but it left Portland by stage coach last week -

I thought so too but some weird shit is going on. With the throttle actuator hooked up it shows 3.5vdc at rest and goes to .1-.2 at full throttle which is right. My min throttle input voltage is set at 3.46 and max at .1, so I found a 1 megaohm potentiometer in my box-O-stuff and put it inline with the throttle input signal wire to the controller and voltage goes up to 9.2 when I add resistance

I disconnected the actuator and on the throttle input wire to the controller, the controller is feeding back 9.2v, wtf? I am missing something. There is a little more to it then that, I have to jump a fail safe to ground before applying a throttle signal but I am not quite sure what is going on. Need to probe around a little more.

The throttle actuator is not a potentiometer either. It looks like an induction coil, mechanically applying throttle slides the core out changing the voltage. Kinda neat.

Well, what I would do is erase the codes and see if they come back. The misfire code may just be an aberration and won't return. The AC code is a bit more complex, but maybe the AC was having a bad day.

If you erase the codes and they come back, be sure to leave them in place and then take your car to a shop. Have a seat in the waiting room, have a cup of coffee or a soda, cross your fingers and say a prayer.

I hope they don't come back and if they do it is an easy fix.

It’s the second time I’ve had the CEL flash in about three weeks. Last time there wasn’t a code at all.

Does the CEL light actually flash on and off or does it just come on and then go away?

How is your car running? How is the AC working?

I have a P0300 code (random misfire) that comes on mrs humfrz's Saturn every now and then. I just erase it and it usually stays away. Sometimes it will come on, I'll leave it and it will go away all by itself - that's happened twice. Does it fix itself or does it just give up? -

These new fangled engines about drive me nuts. Back in the day, when an engine misfired, one would just clean the spark plugs and/or clean the contacts in the distributor cap and that would usually fix it. That was a 15 minute job and it didn't cost nutten.

OMG! - it's ma med time!

nite all

Hall effect sensor. The throttle device is a complicated enough device in its own right. It doesn't just plug in as part of a voltage divider network. It requires its own power and creates the signal for the controller. 86 gas pedal has two hall effect sensors. Redundant for fail-safe. If the two signals don't agree, something's wrong and instead of failing wide open, the ECU just says "nope." I'm oversimplifying but it's close enough.

The CEL flashed for probably ten seconds or so until I started moving again in first and then it went away after I drove down the block. Same thing happened the last time.

Otherwise I think the car’s ok. Gn sir hum.

Well, the new job didn’t pan out. The guy told me he’d keep the resume on file, but I’m sure that was just told to soften the blow.

The good news is that my fiancée got hired at one of, if not the largest trauma centre in Canada. She’s started this week, and absolutely loves it, outside of her current commute.

We found a nice place to rent in Markham while we figure out what the hell we’re doing buying wise. It’ll work out nicely since I’m switching departments with my employer in the spring. Going to join their local field group, so I’ll only be gone a week or two per month. Big plus is that I have a 20 minute commute even during the heaviest traffic, the wife is looking at an hour for worst case.

Unfortunately the landlord didn’t have all of his ducks in a row for the move in date he gave us. We’re waiting on the place to be inspected by the city for occupancy by laws. Should only set us back a week. The downside to that is I’m still out in Montreal and only home once every 4 weeks. This coming weekend was supposed to be my days off, but my boss seems amenable to being a bit flexible with extending my stay here, and giving me the following weekend off for the move. The downside to that of course, is we had the following planned for this weekend: move in on Friday, Saturday I was going to finish my half sleeve, and fiancée was going to finish filling in her full sleeve, Sunday was going to be thanksgiving dinner with my grandmother.

Some wild things have happened lately in both of our family lives, in that both of our parents have done things to effectively make us cut ties with them. I’m sure that it’ll get better with time, but my mother just couldn’t ever be nice to my fiancée since retiring and picking up an alcohol habit. And her parents are welcoming her sister back into their lives after kicking her to the curb years ago for some awfully sketchy shit.

(directed at myself)

I don't know why I didn't consider it is a hall sensor. Yeah, it does pull it's own separate 12v source for the actuator.

It was the factory that suggested I fake a throttle input. I guess I just have to give them a call, but since they got bought by Borgwarner they are a pain to get ahold of.
