Questionget a coffee, this one is long and pointless.
my 99 v70 base wagon is getting a p0130 bank1 sensor1 o2 sensor error but drives like a dream and has no other issues. i think it's a bosch me7 motronic 168hp 5254S.
THANKS FOR TAKING MY QUESTION! i have 2 volvos and they are happy and alive because of this website.
i replaced the front sensor and wiped the code but it comes back, but i have a bit more power in the engine now. or it's just running rich because of the incorrect readings.
otherwise it's more similar to a toyota in maintenance cost and durability. mail-order parts from fcpgroton and advanceautoparts are inexpensive for the non-awd and non-turbo models and i 'think' im staying ahead of the gremlins.
however i did buy 2 cheap universal 4-wire oxygen sensors and spliced them in carefully. ive kept the originals, and the car is running terrific and smooth but the check engine light keeps coming on and advance auto's odbii reader says p0130 specifically bank1 sensor1, rich mixture, circuit error, missfire or fuel pressure.
(i replaced the rear o2 after being told it can be harmless and restore a bit of fuel efficiency and power)
should i hunt down a problem somewhere else like an air leak or fuel issue? or just get the real OEM sensors and be done with it? a tech a FCP told me that the OBDII 99 volvos cannot use the universal sensor but my car is running fine.... am i just asking for trouble down the road?
some more rambling background history 3months ago:
after a long winter drive (3+hrs) one ignition coil died, i got a Bosch V09125601 replacement. i got home and autozoned it and they said 2 or more (ack) coil packs were gone and 02 sensor was bad. so i started to order ignition coils on ebay. i bought all factory original Volvo labeled packs of 2 model numbers. for between $30-$60 each i got 1 more Volvo (not bosch) 9125601 and 4 of 30713416 because i was told they are identical. i hope. the mechanic told me they are interchangable.
also ive ordered and am going to replace the:
fuel filter, air filters, spark plugs (ngk in there now, ordered volvo OEM), suspension and mounts, various vacuum hoses and T's.
these 1999 V70's are a dream to work on. no turbo or awd to clutter up the system and fail prematurely. repairs are intuitive and parts are easily accesible with a jack and common tools.
you are going to tell me to get all the universal aftermarket crap outta there and get OEM volvo stuff right?
for this beauty it'd be worth it since i won't have to spend to repair the AWD or Turbo systems.
Thanks! - Per
AnswerPer, those V70 should be using the denso sensors. Those universal sensors pretty much suck. As a second measure I would check for leaks at the intake manifold. These cars are one of the better ones and have quirks but overall are a decent car. Hope this helped some. No books next time. I ran out of coffee reading this. HA. Roger
