oxygen sensor, service, tracs help!!!!
hi i have a 1998 s70 t5se. and the oxygen sensor, service and tracs lights are on all the time except on rare occasions when they will turn off for around 2 minutes then come backs on. i have change the oxygen sensor by the engine and the light is still on. the tracs never turn off no matter if i push the tracs button. and the service light is just always there. does anyone have any ideas why this happens and anyways to fix them. and also could the abs module be keeping the tracs light on? its last tune up was around a month ago. thanx

I can talk about the ABS/TRACS. My understanding is that the ABS / Tracs are the same. When the wheel spins, the car uses the brakes to slow that wheel. You can buy the module at IPD or FCP Groton. I did not take this one on myself and paid dealer $$$$$$$$ to diagnose/replace. If the ABS module has failed, you only have regular brakes, not ABS.

ABS is pretty important-When the ABS engages, it will sound like a miniature jackhammer (not as loud) and the pedal will vibrate. I dont know if the ABS and TRACS are controlled separately in the module or if one can fail and the other work. This is the hard part, something set the error and if you go to Volvo they will charge $700-$900 to replace the module. My local repair shop shyed away from this. If you can reset the code and see if it comes back, that would be best. I've heard you can do a hard reset by disconnecting both battery cables, wait minute, then touch the 2 cables together, then reconnect to battery-be aware you will need to know your radio code and this will most likely reset all codes / information. I know this does not reset SRS and not sure about ABS- May want to check with TECH before doing this
Anyone else have ideas?

You should probably get a code reader as it may help. Mine is a non turbo 98 S70 and also have an XC70(turbo) but when the front and rear sensors where replaced (make sure you use Bosch) and I cleaned the MAF most emission and fuel errors were gone after clearing the codes. Mine also had air pump errors / that I had to replace the pump, relay and check valve to get a clean scan.
I hope this helps

Hello, I use the equus/innova but unless you get into real high dollar units, I dont think they communicate with ABS/AC/transmission/service light/airbag- mine does not. These will clear most other codes. You should look at IPD but make sure you understand what they will/wont do. Most part stores will do a read for free
