dave seymour Posted July 29, 2012 Report Share Posted July 29, 2012 Hi Guys, My G4 Storm is throwing upÂ two error messages: I have not started the car yet as wanted to rectify these two issues first. Car is nissan RB30det, factoryÂ RBÂ tps and three wire oxy sensor. (Isn't factory only 2 wire?) Firstly AN Volt 3 (connected to my TPS) is saying low volt at gnd. -I have taken a 5 volt feed off the ecu to this device and it is grounded to the ecu also. could it be that this sensor needs a 12 volt supply and the 5 volt is not enough? Secondly AN Volt 4 (connected to my oxy) is saying the same, this also has been connected to an ecu ground andÂ to a 5 volt feed but I think this is quite obvious that it should be 12 volts, just wanted to check with those of you which know before I go changing these feeds. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
