Mr_Flibble Posted June 21, 2022 Report Share Posted June 21, 2022 I have an issue with my ECU, I keep getting; ECU Fault Code 44: An Temp 1 below Error Low value Which is the IAT sensor but it is reading the correct temp. I have disconnected the sensor to verify and the temp reading goes -40 plug it back in and it is reading again but still the error. I have cleared the fault but it comes straight back. Any help please ? Quote Link to comment Share on other sites More sharing options...
Mr_Flibble Posted June 21, 2022 Author Report Share Posted June 21, 2022 It appears it wasn't the iat sensor but the water temp sensor. Quote Link to comment Share on other sites More sharing options...
