i had the check engine light come on today yet again and its coming up with the codes 0500,1492,1693.. i had it idling and it started to miss i figured since i had a spare fuel filter hanging around i swaped it out and it seemed fine after that then on my way home i was driving down the road and my tachometer stopped working and the truck seemed gutless then a few seconds later it went back to normal the check engine light was on again and it comes up with the same codes ....any ideas i really would like to avoid takin it in to the shop but might just have to be ive got lots of heavyduty exsperience but this computer stuff has me baffeled

 

anybody? well i guess its time to break out the wallet an d throw some $$ at it

 

0500 will happen if you had spun a tire, 1492 is accelerator solenoid malfunction 1693 is just a companion code try and restart it 3 times and let it run a minute between starts see if the CEL will go out might just be a glitch could also be a cam sensor maki the tach drop out

 

i have shut it off many times since it has started doin this and the CEL will go out then it will come back on at somepoint allways at different times seems like a sensor to me but all my 12v buddys are convinced its the IP

 

it sounds like your cam position sensor is going.................p1492 is batt temp sensor is too high did you read the codes with a scanner??

 

nope got them of the odometer

 

to get all of them, use a scanner..i'll bet there is po339
auto parts stores will usually do it free

 

0500 vehical speed sensor malfunction

1492 bat temp sensor volts too high

1693 companion code
