Since having the K-Pro fitted I've developed a fault light on the MIL which comes up as DTC P0452: Fuel Tank Pressure Sensor Low Voltage. At first I thought this might be to do with my fuel sender problems but once having fixed that the problem still remain. I can clear it on the ECU with my laptop (and by an ECU reset) but it keeps coming back....
SO...
I traced the wires on the ECU and have found that I dont have any wiring for that sensor going to the ECU :? So My question is - does the DC5 JDM have this FTP sensor fitted? I used the RSX manual for the pinouts cos the RSX has it but I dont think ours does. My old ECU never came up with the fault.
So for information I've collated the RSX manual pinouts with the ones posted by Gonzo a while ago and these are here below. As you can see I dont have a connection on E5 and E14 which are the FTP sensor conns.
Can someone when they are down there have a look at their ECU connector and on con E see if they have wires to E5 and E14.
Thanks...
