reverse not working

[jody78]

I am looking for help on how the reverse works on these 900s. I have a 2005 900 switchback, I removed the engine last week to install new crank seals and now that the engine is back in the check engine light flashes all the time not 3 or 5 times and the reverse won’t work. When I push the button noting happens.
I have the electrical drawing and I have checked all the wires in that system back to the ECU (computer) and they are all good.
Does anyone know how the reverse works on the 900 and what else can I check?
What does it mean when the light flashes all the time?

Whats your idle RPM?

Did you double check ALL your connections?

I have the gas tank out now so i can check the wiring but i think that the RPM was around 1700 RPM. I have checked all the connections and cant find any problems so far. Do you know how the reverse works? Does anyone have the electrical drawing from the ECU connector to the stator?

so the check engine light DOES flash...count the flashes carefully...it will flash "X" times, then have a 2 second pause...

it will not go into reverse UNTIL the check engine light is fixed...your motor is in "LIMP MODE"

The light flashes contionously and doesnt stop. what does this mean

 

[BIGGDAWG]

if you watch the flashing light there will be a slightly longer pause between the flashes that is the break then start counting till the slightly longer pause. there is no code for continuous flash there is a pause you just have to catch it.

it will keep repeating the code. here is the code list

 

[jody78]

thanks for the info, i will look and let you know

if it seams steady then it might be code 1 tps and that is why reverse won't work also.

when i put my engine back in at 2am.. lol probably my problem. but i miss routed my tps sensor wire and it was rubbing on my brake disc. so i would check your wiring. yea code 1 did seem like a constant flash. but mine ran like POOO when i had a tps problem.. miss fires.. bogging at WOT

 

[guidoxpress]

yep, i bet your TPS harness is shorted out, not plugged in, or your TPS sensor itself is bad...

 

[jody78]

I cant find the wiring diagram for the TPS i have the manual for the 900 RMK, but i dont see the TPS on it. Does anyone have a drawing to help me check the wiring.

 

[jody78]

Thanks for all the help, i have found a broken wire on the plug going into the TPS sensor, fixed the wire and no check engine light and reverse works good, now to sell this sled because i just got the new 2011 800 assault switchback, i hope this one runns better then the 900s.

glad you got it going now..

your lucky you asked for help, before you made that comment about the way the 900 runs...

line your new pro up againist my 900 and see if you agree your $12,500 sled has more ballz!!
