O/D off after jumping another vehicle?

  • 1.8L
  • 4 CYL
  • 74,025 MILES
So, I'm not sure if I have two problems or just one.

Car ran fine and one day my husband gave someone a jump start. I would say the jumper cables were connected to our batteries for 10min or more. Not long after I left, I noticed the O/D off light was on. So, I pressed the button thinking I accidentally turned it off. But the light didn't go away. Then it did but came back on not long after and continued to go off and on until I arrived. It didn't happen again then maybe two weeks later he jumps someone else off again the same thing. Now it's like it will randomly go off and on for a few days then stop maybe a week or longer but come back on without us jumping anyone. There is no check engine light on, but We plugged his computer up no codes, tested the battery and alternator. Battery was low voltage. We replaced battery and did the scan again this time it came back with a battery current sensor o believe it was a saved code. It's started to get worse sometimes I'll be on the highway going 70-80 and the O/D off will kick on and slow me way down to like 50 which isn't save on a busy higher.

Now I've noticed when the O/D off light is not on. Sometimes my RPMs will kind of jump back and forth or they will get up to like 5 before shifting. But every time I'm on the highway as soon as I hit 70 mph the rpms will like flicker from 3-4 and seems like because of that its having trouble shifting but I'm not sure if that's the little tug or pull I feel. Now if the O/D off light is on this doesn't happen and vice versa so I'm not sure if these are two separate issues or one issue together, please help.
Do you
have the same problem?

If this started after jump-starting another vehicle, I suspect it is going to be an electrical issue.

Question: I noticed you scanned the computer. What type of scan tool was used? Is it a scan tool that can read can-bus codes?

CAN stands for controller area network. Basically, the different modules are tied together via a few wires. This type of scan will retrieve codes from any of the modules storing them. If a traditional scanner was used, it would likely be limited to engine codes.

Here is a link showing how to scan the can-bus. Let me know if this is what was done.


If it wasn't done that way, that is where I would start. There are different things that can cause the OD to fail.

Let me know.

Was this
