Just the other day I got the red triangle of death and a check engine light. The car felt like it would barely move, but luckily I was close to home so I coasted it. Pulled the codes and they are coming as p0a4c and p0a4d. Looking around, someone else had a similar problem and it turns out some rodent ate away the harness. However, I checked under the hood and couldn't see any of the harnesses eaten up. The next day, I started the car and the triangle of death went away. I cleared the codes and now it runs fine. Super random. Has anyone else ever run into this issue? I tried to look around to see if maybe it's a bad sensor issue. Also, I replaced the electric motor a couple months ago and added over 15k miles since then, so I don't think it is related to the motor. I would like to get it resolved so I don't end up stranded one day on the side of the road on a long distance drive. Thanks!
P0a4c Generator resolver output is out of normal range P0a4d open or short in generator resolver Trouble area Wire harness or connectors Hybrid vehicle generator HV control ECU I'd be looking for wiring issues SM-G960U ?
Yep, I recently pulled the transaxle and swapped in another one with lower miles and filled up the transmission oil with 4 qts / flows out of the top hole. It's been running fine for 15K miles. My friend who works as a mechanic at Toyota told me to clean the plugs and change out the fluid again. So I cleaned out the plugs for both resolvers and changed the transaxle fluid and the light no longer pops up.
