Question about 1999 Buick Century

HOw do you clear the Diagnostic Codes

I had a diagnostinc done on my 2001 Biuck Centry, came back with the speed sensor, which is the same thing they we got when we put the reader on it. But now we need to clear the codes, to put the reader back on it, to make sure what we fixed was what was throwing the codes. We unhooked the battery for about an hour, took the fuses out, we are scratching our heads on this one. How do you clear the codes??? please advise

I have a trouble codes p0717 and p0700 on a 2006 Cadillac cts 3.6 the car shifts crazy and while pushing on the brake it locks up anyone know what's going on please help

P0717 is for the transmission input speed sensor , which inturn will bring up the other code P0700 for the Trans Control Module , so i would suggest having the codes cleared and see if they come back as sometimes a glitch can occour , if codes reappear and so do the symptoms i would replace the input speed sensor , it reads the primary pulley speed and sends info to the TCM and as far as i know there are no diagnostic s to carry out as this sensor either works properly or fails so get it changed and hope its not the TCM as well, keep me posted if you wish

Cummins diesel in 2001 Dodge is cutting out and mild surge. code#s are P0500,P0370 P1693

you have codes related to the pcm, transfer pump and a vehicle speed sensor. these could be related or all individual issues. related issued could be wiring, untill you start doing testing it will be hard to tell.
start cheap and test the speed sensor first, then you can clear the codes and continue on any codes come back.

Disconnect the PCM harness connector(s).
Disconnect the Vehicle Speed Sensor harness connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance of the 5 Volt Supply circuit between the VSS harness
connector and the PCM harness connector.
Is the resistance above 5.0 ohms?

My speedo is not working on my1999 chevy venture. The van sat for 5 months while the head gaskets were being change. All is now fixed and running great except for the speedo not working.All other gauges...

Just to clear things up, there is no such code as "502" on a 1999 Chevrolet Venture. There is however a code P0502, which is low input for the vehicle speed sensor. This may sound like symantics, but it can make a huge difference when you are trying to diagnose fault codes. There is also a B0502 that is a possible code on that vehicle, so when you post a code, you need to post the ENTIRE code number including the prefix letter. (there are also U-codes and C-codes used on that vehicle)

Anyway, I'm done preaching...back to your question: Your vehicle speed sensor (VSS) probably got unplugged when the work was done and someone forgot to plug it back in.

The VSS is located in the transmission housing on the right side of the vehicle near where the right axle shaft goes into the transmission.

Codes don't show up

p500=Vehicle Speed Sensor Malfunction (VSS)
p1540=VSS Signal Too High
P1507= Vehicle speed/Idle Speed Actuator
Speed sensor is faulty or has a bad connection.

You may have a bad wheel speed sensor. only with a scan tool that shows data will you be able to determine if its a sensor issue or computer or gauge issue

I put a new speed and change sensor for my 1994 chevy silverado l

if you put in speed sensor make sure you didnt cross thread the sensor this would be bad
if you also got a code for the speed sensor remember you have to clear your codes when your works done but before you clear them right them down so you know what codes was in your truck use a scan tool to clear codes
