AlexSavv Posted February 2, 2019 Report Share Posted February 2, 2019 Hi guys, sorry for the noob post but.. I’m wiring an oil temp sensor to my Monsoon using a spare AN Volt channel set as GP Temp (external pull-up) Im using a 2 pin temp sensor from EFI parts, https://www.efi-parts.co.uk/index.php?productID=125 I have wire the sensor in the following way: 5v (with external 1k ohm pull-up) and AN Volt 4 to one pin... sensor ground to the other pin. Ecu is giving me a fault code saying AN4 at 5v... any ideas what I’m doing wrong? Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 3, 2019 Report Share Posted February 3, 2019 Your wiring sounds correct from your description. The 5v error usually means there is no sensor connected/open circuit. I would start by unplugging the main ecu connector and measure resistance between the sensor ground and the analog volt pin, according to their data sheet you should see about 800ohms (@20deg C) if wiring and sensor is good.
