SOURCE: i Have a 1171 code on a 1999 xc70 volvo and the

The control module receives information from the heated oxygen sensor (HO2S) about the fuel/air mixture when idling at both the lower and upper part-load range - If the fuel/air mixture deviates from [lambda]=1 the short-term fuel trim will compensate for this by adjusting injection time so that [lambda]=1 is achieved. When the short-term fuel trim makes an adjustment, the integrator median must be adjusted by the long-term trim. Diagnostic trouble code (DTC) ECM-261A will be stored when the long-term trim must be adjusted to maximum in the lower part of the load area.

SOURCE: My xc70 Volvo shows a message "bulb failure

"position light" is a rear parking light which has failed or become unseated. Sometimes you can knock on the tail light housing and they will come back on, but they burn out shortly after regardless.

These and the low beam headlamps fail very frequently on these cars so you should become familiar with the replacement procedures.

Check the online manual:

Awd on 2004 xc70 quit working--any ideas ?

Raise the vehicle and start the engine. Put the vehicle in drive, make sure that if the vehicle is equipped with DSTC it is turned off. If the front wheels turn but the rear driveshaft doesn't, the most likely cause is the coupler between the transmission and the angle gear is bad.

Volvo 1992 XC70 AWD radiator fan doesn't shut off draining the battery

It is likly a dirty relay. This is located on the passenger side by the ratiator fan, with a black plastic cover over the box. Be sure to disconnect the negetive side of the battery before working on any thing electric. Clean the relay contact points using 200 grid sand paper (wet-dry black paper), You can use a spray electric contact cleaner as well, which you can get at most autoparts stores.

I have a 2001 Volvo XC70. It has a trouble code

Well this can be caused by the thermostat being stuck open. The coolant temp will not come up to expected temp. It can also be caused by the fan being stuck on. Run the car and see if the fan stays on. If the fan is not stuck on it may well be the t-stat and replacing that should cause the check engine light to go off after a drive cycle.

Volvo XC70 I have had several computer errors

Check two items, chassey grounds by battery, transmission and starter. Also, check to make sure the alternator is providing enough voltage, should be around 14 amps. Had a similar problem with my 2002 XC70, replacing the alternator fixed it! I used the Car Talk website to find a good local mechanic vs. the stealer.
