Finally it's running!

Post by subzerocarfanatic » Thu Feb 13, 2020 8:33 pm

:)

I was beginning to wonder if I would ever make this post. I finally got it fixed the electrical problems I was having, low voltage throttle pedal fault codes on the vidaDice and everything, the problem was the the guy installed a used OEM Volvo accelerator pedal, but the plug was wrong. So he had the female end of the wiring harness all messed up, and the wires inside the harness were pushed in so they weren't making contact with the new throttle position sensor on the new pedal. That's why I kept getting the low voltage fault codes from the Vida Dice.all the fault codes I was getting from the vitae dice we're all related to the accelerator pedal and the etm electronic throttle module, and after doing the test suite tests on the vital dies for the electronic throttle module I knew it was good because both potentiometers were in sync,so I knew it had to be something with the accelerator pedal wiring and I knew the pedal was new so I started looking at the wires and that's when I found it,I just had to cut the male harness plug off the old one and wire together on the new one to make it work, because he had the male harness plug on the new one so messed up it wouldn't work at all it's all working now the ETS light went off and the accelerator pedal is very responsive. I could not be more happy. For the first time in three months the car is running like it's supposed to. I want to thank everybody on the forms for all their help, I don't think I could have done it without you guys. I will post some pictures maybe tomorrow of stuff of what I fixed.

Thank you, and yes it did, I had the entire contents of the engine wiring harness pulled out of the car in 6 different ways and went over every single inch of every wire ,harness,plug etc and could not find the short or voltage loss.Well one good thing,every single plug under the hood from injector plugs to MAF sensor plug has been cleaned with CRC electronic cleaner then squirted CRC Dielectric grease in every female plug end.All the wires were wrapped with new electrical tape, new wire loom,new batter connectors soldered on, all frame grounds cleaned and tightened, the entire front suspension components including brake rotors,pads, SACHS front and rear shocks/struts are now replaced with new and the steering rack was pulled out,flushed and cleaned with new fluid and bellows, all of this came about because while i had the radiator and fan and all the engine out i figured i would go ahead and replace everything because it was all worn out, poor old C70 was neglected bad, not anymore though, i think I am good for a long time now i hope, lol.

I would love a C70 but can't fit my large bulk and height into a coupe or convertible. Good luck for the future, ,and all that future proofing you have done will be worth it I'm sure.

I sure hope so, it was worth the extra time and money to do it while I had it all out anyway and majority of the parts looked original like they have never been replaced in the poor cars life, I have always believed.....if you take care of your car it will take care of you, so I don't understand the neglect mentality that most people have.They just get in it and drive it and don't worry about anything until it's to the point the car breaks down. Preventative maintenance goes a long ways.My wife is so excited,tomorrow will be the first time she gets to drive her car,I bought it for her as a wedding gift and it was parked 2 days after we bought it, I bought it in late September early October sometime, so here the middle of February hopefully no more issues,she can finally enjoy driving it. I have spent more in parts then I paid for the car,lol

It isn't uncommon to spend more for the parts than the car is worth these days.

That said, for the fanatic in us, it's worth every penny =)

I have spent more on the last 4 P80's I've owned than any of the cars were worth. Those regulars here know how much my 'R' has cost and it is in the 10's of thousand $$$'s. You are right that many people just run them into the ground as cheap cars and unfortunately as they tend to keep running even with bad issues, they just keep going. Added to the lack of knowledge by many repair shops the repairs can sometimes be poor to awful.

Apologies if I have told the story before of a former colleague in the US around 30 years ago. She called me one day to ask advice on why her car was running poorly. It was a Ford Escort from the late 80's she had bought new. I asked her the mileage and what servicing she had done on it. She said it had over 150,00 miles and had NEVER had a service or oil change. She just added oil as it was needed!!!

I suggested she took it for a major service and then the repair shop could then see what they were working with. Strangely they car car was running great once serviced.
