Buick Repair Questions? Ask a Mechanic for Answers ASAP
I left the car at a friend's place 30 miles away yesterday and I have not been back yet; please cancel my inquiry for now. I am also in the process of signing up for the monthly
plan. I will return to this space after I check out the car tomorrow. Must attend New Year's dinner to-day at Mother-in-Law's.
Hello, gmwrench; I'm back...
I went to the car the next day; the gauge was down to cold, so I started the car.
It ran fine, so I headed for home- 50 km./ 30 mi. away. After 4 or 5 mi. (when it warmed up), the gauge trotted on up to HOT and she lost her get-up-and-go, as before(engine protection mode).
I pulled over, opened the hood and disconnected the wires from the Temp.
sending unit. I then tested the harness as per my Haynes shop manual– run a jumper from the green wire terminal in the plug to ground. Nothing. The dash gauge didn't
move. So then I thought: I'll just leave the plug off and drive 'er home like that.
Wrong. Now it wouldn't start at all. Finally, I put a jumper between the green wire and
the orange w/black wire in the plug. It seemed to work: I drove home, the car ran well,
the Rad. cooling fans operated; I drove some to-day, also. What does this mean?
im sorry i missed that post
do you have any access to a scan tool so we can perform a needle gage sweep to see if we have a cluster problem or wiring or computer problem?with that sensor plugged in we need to know if the PCM is getting the correct tempature reading.the computer gets the temp reading then sends that to the IPC gage cluster.
I have a CAN OBD2 tool, but I'm not very experienced with it. Tomorrow I'll hook it up,
reconnect the plug to the Temp. sending unit and give it a try.
I have the manual for theOBD2 but what should I do, in what order? Start the car?
Take readings first? Warm the engine up...???
I'm sorry I haven't gotten back to you; I've been busy day and night for the past week:
gas tank on my Mazda pickup, wheel bearing/hub on my '97 Buick and thus brake service, Wife in hospital, work – the list goes on.
I am on the Just Answer monthly pay plan, so I will get back to this issue soon, maybe this week-end.
