Volvo S80 - Recent Questions, Troubleshooting & Support

Why do you beleive there is a fault in the wiring?

2000 Volvo S80 | Answered on Jan 29, 2019

I have an S80, never had a problem. It's possible the key battery has "expired". Try your spare key. What about the car's battery if it is not good there may not be enough power to allow the Key to function properly. Are you sure it is the proper key? Antitheft and security features may require help from a Volvo dealer!

There may be problem with the mass air flow sensor (very common with Volvo). This causes the fuel system to malfunction.

You may have noticed increased fuel consumption, loss of power and general 'lazyness'.

Better to take it to authorized Volvo service for a checkup/fix.

Is there any problems with the car?
I'm assuming you mean the service engine soon light.
take it down to a local shop, and get them to put a scanner on it.
It'll show why the light is coming on, and from there you can decide what you need to do to fix the problem.

Hope this helps :)

changed the wrong sensors
the code (p0057)refers to the heated oxygen sensor (HO2S) which is in the exhaust manifold before the cat converter
code p 0172 refers to system too rich bank bank 1===causes ---intake blocked ---EVAP canister purge valve --- fuel pressure---EGR systems ---injector/s---HO2S
If you replace the HO2S sensor/s then that will [robably fix all codes
the heated oxygen sensor reads the exhayst gas and reports to the ECM to adjust the air /fuel ratio to get the engine to run within parameters
when it is not working , it runs lean or rich

indicates what you suspect
the noise could be sump pressure trying to pass the faulty PCV valve and pressure in the sump will blow oil out of weak seal and gaskets

If you're finding it difficult to service/repair your car, get one of those online manuals. You'll not have to wait for others to answer,
or rely on mechanics and all. Plus I know a website that has very good manuals online, without expiry i.e. for lifetime.

if the rain drops are falling on your head , it is unlikely that it will be the sun roof
more likely door drain holes blocked or plastic covering that covers all of the holes in the door has not been replaced allowing the water into the car behind the trim
another point for water is blocked drain for the ac evaporator box so check that hose as well

its not reading earth the throttle position or the abs. or can even be the engine revs. low voltage can be a problem that causes this. a bad connection or even a faulty alternator. turn off then back on again is resetting the power and the longer on the weaker it goes to. like a bad regulator.

2000 Volvo S80 | Answered on Feb 12, 2018

Sounds like the large power wire (starter wire) is routed too close to the VSS. Sounds silly, but it can keep the engine from running.
