Luis Lopez Posted July 21, 2019 Report Share Posted July 21, 2019 Hi guys after rebuilding my motor I tried to start the car and the ecu showed crazy errors. 5V supply error. AN temp 1 and 2 above error high value and some others like the on board map reading crazy numbers with the car shut off the tps also reading funny. Car is an 2003 Evo 8 USDM. Any help will be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 21, 2019 Report Share Posted July 21, 2019 Check the 5V out parameter on the runtimes screen, ECU status tab. Check it is showing near 5V. If it is not then you have a short on the 5V power supply somewhere. Quote Link to comment Share on other sites More sharing options...
Luis Lopez Posted July 21, 2019 Author Report Share Posted July 21, 2019 Hi thanks Adam. Just got it fixed somehow my dumba$$ swapped all the 5v in the pressure sensors where the ground is supposed to be. Quote Link to comment Share on other sites More sharing options...
