Need help with 2E82
Hey guys. Just wanted someone to help me claify something. So just tonight went to move my car and the fan was going super fast and loud. Definitely didn't sound right, this was shortly after I started the car. Car was cold. So I pulled the codes and got
2E82 electrical cooling pump : switch-off But when I did some research, that code people are listing as electrical cooling pump cutoff - over current. Drove it this morning, fan would go full speed when the fan would turn on, monitored my coolant temps and it never went past 205 all the way to work, 20 minute drive half city half hwy.

Yeah got the pump replaced and did the thermostat as well at the same time. Was just curious because my code listed as switch off and most people. It says over current

Just got these 2 codes. 2E81 and 2E82. I noticed the fan running high speed so I hooked up MHD and monitored coolant temp. It never got over 200F but the fans run high all the time. No cel or limp mode. I'm assuming the WP is going bad but still working for now? deleted the codes and will see how fast they come back. Darn thing is crying for something again. I cant complain too much as I havent done anything but maint for the las year and a half on a tuned 335. Time to open the wallet again.
