Fuel Pressure Sensor Fault Code on Kpro

fonz600 · Post by **fonz600** » Thu Mar 27, 2008 1:04 pm

I keep getting a MIL and Kpro says it is Fuel Tank Pressure Sensor Low Voltage.
My battery is fully charged and it's only started to show this fault. Car is starting to get on my fecking nerves now as it's one thing after another.
Any ideas on what causes this and what the effect of it is?
It wouldn't effect my fuel gauge would it?
The low fuel warning light comes on when the needle reads 1/2. The light is correct tho which I found out to my embarrassment when I ran out of fuel

What vehicle is this? The ecu has nothing to do with your fuel guage.

im curious as to what wiring was played with or changed in the car? i answered your thread on another site too dude. but i never asked this. the fuel gauge and fuel pump wires in the harness are both yellow , different color stripes. if no wiring in the car has been changed , this is an odd problem.

I'm not sure mate. The more I do stuff to the car the more I realise the conversion wasn't a good one and I'm going round fixing previous "experts" mistakes.

I believe that there is no fuel pressure sensor in a Japanese CTR. You will have to disable emissions error checking.

i told him on clubrsx or k20a to do the same thing , disable obd2. you are right spunk , there is no FTP or as Kpro calls it Ptank on the JDM models. the JDM models always ran a few sensors short than ours.

You told me to disable OBD2 as I didn't need it. Spunkster told me to disable emissions error checking as the JDM didn't have the sensor.

I wasn't gonna disable without a good reason. Saying I didn't need it isn't a reason in my book as I was assuming OBDII was there to pick up faults so would leave it switched on unless there was a good reason to switch it off.

power to ya , lol. and disabling obd2 , and disabling emission error checking is the same thing dude , just so you know , lol.
