I had a Superlift Truespeed installed a week ago.
One of the wires came loose, resulting in no speedometer (and therefore, no cruise, trip computer, odometer, estimated fuel mileage, etc).

Just for fun I pulled the codes (on-off-on-off-on) and got a P0500 and P1693
No Vehicle Speed Sensor Signal, which was expected.
The Check Engine light never came on though.

I took it back on Monday and they fixed the wire and everything has worked since then.

Just for fun today, I pulled the codes again to see if they cleared themselves and they hadn't.

Is this a code that should reset itself after 3 starts
or will I have to take it to Autozone and have them reset it?

thanx

I always get those two codes. If you disconnect your batteries for a bit, this will clear them. I was doing it, but they always seem to come back ???<br>I finally quit worrying about them. Performance doesn't seem to suffer.<br><br>S.C

 

I understand disconnecting the batteries for 20min or more will reset everything to default settings and clear fault codes.

 

I checked for codes today and it appears that the 0500 and 1693 codes will reset themselves given time.<br>Just not sure how long it really took as I haven't checked in a couple months :

 

Maybe I'll just check every now and then too see if they've cleared.<br><br>Does anyone know which speed sensor causes the P0500?<br>The one on the rear differential or the one at the tail end of the tranny?<br><br><br>phox
