Mystery electrical problems
#21
I took a break from this situation today and replaced the odometer gear because I have been meaning to. Tomorrow evening I leave for vacation but will have my laptop. After replacing the odometer gear I went and got my codes read. I got the codes: P0101-Mass or volume air flow A circuit ranger/performance
P0172-Bank 1 system too rich
The last time which was about 7 months ago I got the following:
P050P-Idol system speed sensor
P0172-Bank 1 system too rich
P0131-O2 sensor
P0102-MAF/VAC sensor
P0108-MAP sensor
Oh, want to see my odometer gear?

Ive been told to replace my starter solenoid and my ignition switch by so many people on 4 different forums dedicated to Volvo's so I am thinking I am going to go with the starter solenoid first. I have check most of my grounds I have one left and its tricky to get to.
Sure, as tech mentioned in post #7, make sure the positive terminal connections there on the solenoid are good and tight, but the solenoid itself only connects the battery to the starter motor (when energized).

Someone is going to have to explain to me how a bad starter solenoid could cause a power failure as described in post #1 of this thread...

Back in the day when i was rolling in a 740, my notice that it was time to replace my battery was a total shut down while driving. I would be driving down the freeway or somewhere and the car would just shut off. I would then start it back up while still rolling and keep going. I would then get a new battery within days and was good to go.
Sounds to me like there is something shorting out the car somehow. I spoke to a guy a few days ago that had a ghost with a 940. It was shutting down for no apparent reason and they found some electrical connector hanging loose in the engine bay that was grounding out causing the fuel pump to shut down. They taped up the connector and the problem never returned. One of those connectors that are not connected to anything for some reason. I see several of them in my engine bay from time to time.
My guess would be that there may be something in system somewhere shorting out the car, likely through the ignition. I recently replaced the light switch in my 960. Actually repaired it. Was causing lights to go out all over the place. Was not causing a stall though. If the only thing you touch is the light switch to cause the problem then something in that system needs to be fixed. Maybe you have a wire under the car somewhere that turning on the lights is allowing electrical flow into some other system because the wires cross. I wish you well. Hope you have a great vacation.

NO
NO. it is not the radio . try making sure the connector on the switch is on good . take the cover off and wiggle the connector and turn the key

Someone posted a link somewhere maybe another forum, but it was all in German, plus they were sold out.
