TPS code first, then O2 sensor bank 1 sensor 1..
I may have to wait until the tester gets here to recheck. The Tech said TPS, then O2... I replaced the air filter, and bought some fuel injector snake oil (lucas) and was thinking about running seafoam through the vacuum lines.. Don't want to damage anything so I will wait on that though.. |

If they were cleared see how fast they come back.
|
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
Takes about 30 seconds, then they pop back up.
|
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
TECH- Thanks so much for your help first off.....
Couple developments, I inspected the ABS module today and all the soldiering looks fine, The unit is remanufactured and looks like new... ALTHOUGH while sifting through paperwork I noticed that 4 weeks ago the brake pads were replaced along with the Rotors were replaced.. How do you diagnose a damaged sensor?? From reading the sensors can become damaged during brake work correct? Thanks again.. |
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
Possible but slim chance. You can Ohm the sensors to test them.
I would try to find a used TPS to try. You might want to replace the O2 as well if it comes back right away. |
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
Will an 850 TPS work? The bone yards around here only have 850's..
|
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
I think it will you might want to double check the part #.
|
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
Same Part Number.. SWEET.. On the way to the junkyardfirst thing in the AM. I'll check back.
|
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
Great! I used a TPS out of a 1997 Turbo 850 and the part # was exactly the same. I put the TPS in my s70 and cleared the codes. The Check engine light went off for about 40 minutes but came back on. I read the codes again with my handy dandy reader- ONLy 1 code now.
02 sensor- Low volts bank 1 sensor 1. I pulled a sensor off a 1995 N/A 850 in the hopes it may function. I may put it on tomorrow to see if it makes the 02 code dissapear... What would cause low voltage to the 02? |
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
The sensor being bad.
|
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
Cool, I'll put the other one in. I picked up the TPS and the 02 sensor for $6.00.... I love the local junkyard... ;)
|
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
That is a great price!!!!!!!!!!
|
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
They had 2 turbo 850's and 2 N/A's.. One Turbo was in great shape, I couldn't believe that that the car was there, it looked great.. I wonder if the engine had given out...
Any other bits I should be pulling off these cars at rock bottom prices? I figure i'd rather have a box of spares..... Especially at $3.00 a sensor. |
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
Maf, and maybe a few other things you think you will need.
|
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
So does the MAF always throw a code when it goes bad?
|
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
Not always but most of the time it does.
|
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
Cool. I ended up buying a Brand New Oem replacement O2 sensor.. The MAF doesn't seem to be malfunctioning.
|
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
OK cool
|
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
Well the O2 sensor seems to have done the trick. The car no longer smells abnormally rich. Pretty much runs like a new car!
|
RE: 1998 s70 ABS, Check engine, flashing Arrow ??
Glad all is good!!!!
