Thank you so much for the reply.
The pin outs on the ecu side i do have. Thats what i used originally and it has worked fine for about the last year and a half(using the factory harness). Im suspecting the wiring in my stock harness from factory. I now want to run new wires directly from my vipec ecu to my TB and the same for the FPS. I was wondering if anyone had the diagrams for the actual TB and actual FPS pinouts so that i can connect on the actual pins and on my ecu.
I have been getting these errors mostly, hence why i suspected the TB but now with a 2nd fresh one from another car im getting the exact same... the car will idle fine...then suddenly rev to 4000rpm... i get an error and it would go to RMP limit. Cycle power on the ecu...clear faults then its fine again. sometimes i can even drive around the block with no issues..other times 4-5 ecu power cycles are needed just to get to the end of the street. ive even once had a error at the fps ground
Voltage at tps main after calibration with pedal at rest reads 0.74v tps main and 1.59V at tps sub..which is strange that they vary so much..when i go full pedal they read 4.35v at main and 4.48 at sub.....which is alot closer that at 0% pedal.
The voltage on fps at rest is 0.69v on main, 0.67v on sub...and at full pedal 2.94v at main and 2.94v at sub.. they track each other perfectly all the time...dunno where that one fps ground error came from... i did change the error values on the FPS sub and main to 0.00 and 5v respectively to test and since have not had any fps errors and watching the values on my laptop while testing they seem pretty solid.
but mostly i get these errors..all surrounding the TPS.
One thing to note... when the car sits and idles...it shows actual tps value at 4% wich is where my base map is at... then when it suddenly revs to 4k that value doesn't change...which is weird. we all know the only way that engine revs that high is with added air so the TB plate did move but nothing registers on my live run time values... both the Throttle bodies that i have now has done this so i cannot believe that they both have the exact same fault?
Foot Position (Main) Signal at ground.
FPS(Main) signal has been less then the specified “Error Low” fault condition for this channel for a continuous period of a more than 2 seconds.
Foot Position (Sub) Signal at ground.
FPS(Sub) signal has been less then the specified “Error Low” fault condition for this channel for a continuous period of a more than 2 seconds.
Electronic Throttle Position Control Error
Throttle Plate Position unable to track Target Position. In this fault state the throttle plate cannot maintain or achieve the desired target position. The Throttle Plate position and Target Position in steady state condition must remain at ALL times within +/- 2% of each other. When the Target position is changing the excepted tolerance is adjusted based on its rate of change. If this tolerance is exceeded for a continuous period of at least 2 seconds this fault code will be generated.

Check mechanical operation of throttle actuator.
TPS Main and TPS Sub tracking Error
Throttle Plate Position Signal Tracking Error. Expected relative position between TPS (Main) and TPS (Sub) has exceeded the specified tolerance of +/- 3.0% for a continuous period of more than 2 seconds. In this fault state the ECU must assume the throttle plate feedback to be invalid and that a problem exists with either with the TPS(Main) or TPS(Sub) signal. The ECU cannot detect which signal is invalid which means the plate position is effectively unknown and cannot be controlled.

FPS Main and FPS Sub tracking Error
Foot Position Signal Tracking Error. Expected relative position between the FPS (Main) and FPS (Sub) has exceeded the specified tolerance of +/- 3.0% for a continuous period of more than 2 seconds. In this fault state the ECU must assume the foot position feedback to be invalid and that a problem exists with either with the FPS(Main) or FPS(Sub) signal. The ECU cannot detect which signal is invalid which means the foot position is effectively unknown. At this point the ECU will force a fault condition value to 5.0%. It should be noted that in this fault condition the ECU still has control over the throttle plate and this will continue to be controlled as normal which also means the Electronic Throttle Control isolating relay will remain ON.
