Re: Ongoing issue with Transmission Range Switch

Like Rick said, if everything else has been replaced - the most difficult happens to be what is left.

I'd like to smack the person that created CARB and some of the inspections with a 800 lb FROZEN tuna.

Back in the 1950s the car industry funded shill pieces to tell Us that smog in LA didn't come from cars.

I had this issue in my '96 850 a few years back. I replaced the PNP switch which improved things, but what really solved it was finding the melted wire short in the harness going away from the PNP switch to the ECM. Found it by looking for shorts to ground on the harness. I'll separated wires and reinsulated them, whamo problem went totally away.
Looking for a V90 to be my next Volvo, at the very least a T5.

2017 XC90 Inscription - My best Volvo by far, but Ex-wife departed & I had to sell. 😕
2001 S80 T6 - rebuilt trans, head gasket, fixed & sold
1997 V70 - kid car, sold
1996 850 GLT - found under bridge, 2 year refurb project, commuter car, kid car, T-Boned - SIPS saved passenger. Totaled.
1997 VW GTI VR6 - exceedingly fast.
1971 VW Type II/231 - it was pointed out by management that the children would be killed in it.

I think I found the issue... upon replacing the PNP switch, I noticed that a pin on the connector was pushed in.

10 drives and no issues so far!

Wow, well done! Hopefully you have finally found the problem. That is very well found and it has taken a good eye to find it.

Let us know if it all stays good.
