2003 Subaru Outback speedodemeter stoped working

It could be a speed sensor we would have to first have the computer scanned for codes.It might need a professional scan tool to scan all the computers.You can first have the auto parts store scan for codes and see what come ups.Please give me exact code numbers not code descriptions?

ran a dts scan come up nada,but has ersp in odometer speedodmeter. it worked great yesterday no indication that there was trouble. as I said there is no codes at all.

do you think ,as im sure you have seen something like this before it could be spedo. heab? there are are some thread indicate this scenero,what you think?

DTS scan?Are you using a scan tool that can read all the computers in your car?There is no replace this fix first thing is making sure there is no code in the computers that will lead to a trouble tree.

saturntech9,i am using tyhe same scan tool auto zone use if I took it to them as you said to do.so far since I started using it has scaned trans. brakes,and motor related problems. a z is local parts store. it is an actron scanner.i checked Subaru forum an didn't get any help.

Which model do you have that scanned brakes?Also I said start with the auto parts scan tool and you might need a professional scan to read all the computers.Can you read live data like vechile speed?That would really narrow things to know the speed sensor was giving readings too the computer.What's bad for diyers is the newer cars need advanced Nprofessional scan tools to work on them a lot of the times.not diyer scan tools they sell or use at the auto parts stores.

sorry about the brake scan errow ,it scanned the r.hub sensor.on another vehicle. at this point I hooked it up to check speed and the speedometer started to work,went on test drive unplugged scanner and speed odemeter stopped working again.did this twice speedo. worked fine with scan tool hooked up.beats me .in real time every thing shows good on scanner.

It sounds like a ground issue since it works with the scan tool plugged in.What size engine do you have?

the motor is a 3.5

where do you think the bad ground would be and the scanner is telling me that theres a PID but it wont read do you think that has any thing to do with it

Do you mean a 3.0L engine? So you have a code you can't read?In history or current code?I am trying to find the wire diagram to try to figure out where the problem is.

sorry about that,s.tec is 3.0. when I scanned last it read pid detected but will not respond to scanner. this is basic,as to response from scan tool.does not read mfg. code.

That's typical of the basic scan tools forgot to ask traction control or no traction control?

its all wheel drive and does indicate traction control in dash with button depressed

Check the two grounds shown in the diagram I posted make sure they have 2 ohms or less to ground on all ends of the wires.

STEC9,GOT A BETTER SCANNER THAT PULLED UP THE HIDDEN PID .INDICATED PROBLEM WITH PIN ARE WIRES IN SPEEDO HEAD.MOVED PINS AROUND , AND IT WORKED A COUPLE BLOCKS.I GUESS MAYBE THE HEAD?

Sounds like a loose terminal at the instrument cluster connector.

Saturn tech9,tried to get back to you before but internet lost me for 3 days.i wont to thank you for all the time and help. the #@$%%%$$## ground from factory, on battery was cracked. I had cleaned it and replaced battery a couple wks ago.it must have broke and I did not know it,felt tight. its worked for a week,fingures crossed, so far.

Your welcome glad I could help.
