So 2nd time car went into limp mode then, refused to restart the ice. Clean MAF sensor, car burns oils, so I check it daily. never let the car go below 3 bars of gas. 290xxx miles. This last time it did it to me, I put on a jump starter battery pack on the 12v battery and the car fired right back up. What is weird is I put a volt meter on the battery and it reads 12.6, I go into service check page (flipping the light switch on and off) it reads 11.6. any help would be great.
btw the 12v is a yellowtop, that is about a year old, and the main battery pack was replaced with one of the newpriusbatterys cylinder battery packs. It was running great until I ran into this.
But the battery is reading 12.6 with nothing on and it reads 14.1 when idling. So maybe the battery cables? It's receiving a charge when driving.
i would take it to an auto parts store for a free load test. worth checking the cables for cleanliness and tightness, especially neg to ground point. check the voltage at the front jump point with the car off
