Ok, so i just got home and did my nightly check of DTC's on my interceptor gauge, and code P0503 was on the list. I did a quick google, and it says something about vehicle speed sensor in an automatic transmission??? Anyone know what this code really is in these cars?? Im going back outside to double check and make sure thats what it was...

So upon further searching of the code, its for "erratic, high, or intermittent" VSS... anyone else ever have this problem??

 

P0503 Vehicle Speed Sensor (VSS) Circuit Intermittent ECM, PCM

Your sensor could be going bad, happened in my truck..

 

^what he said, he sounds like he knows what hes talking about, lol

 

well, i did just roll over 70,000miles tonight...

 

Your ahead of me, I would call the dealer and ask them other than that I have no Idea lol

 

guess i'll just clear the code and see if it pops up again...

its probably that crazy 1st to 2nd gear burnout i did when i left a redlight earlier...lol i was testing the clutchs holding ability...it worked pretty well

Ever since i got the header and DP on, the car is a LOT quicker than it ever was...

 

here ya go this is the description for P0503 CEL

Circuit Description
Vehicle speed information is provided to the powertrain control module (PCM) by the vehicle speed sensor (VSS). The VSS is a permanent magnet generator that is mounted on the transaxle and produces a pulsing voltage when vehicle speed is over 5 km/h (3 mph). The AC voltage amplitude and frequency increases with vehicle speed. The PCM converts the pulsing voltage into km/h (mph). The PCM supplies the necessary signal to the instrument panel for speedometer, odometer operation and to the cruise control and multi-function alarm module.

If the PCM detects no vehicle speed for a specified length of time, while other sensors indicate that the vehicle is moving, DTC P0503 sets. DTC P0503 is a type B DTC.

 

Notice your speedo being off recently?
