Just in the very early stages but after having my motor running earlier today ive changed a few bits and now i have no start up...

First thing i wanted to do today was calibrate the TPS and so after setting the low and high reading in the paramiters i noticed when i pushed on the throttle butterfly the MAP on the sensor window was starting to change values...

So i guessed i had the two MAP and TPS mixed up... i swapped the plugs and then when i pushed down on the throttle the TPS figue was now changing..

so after this i read up and realised ive not moved the MAP onto the IM after fitting the RBC... moved that and blocked the old hole.

I get a MAP reading of -29.5 and then when i try turn the motor over i get a reading of 9 hundred odd?!

The TPS is reading 40 & 110

The motor no longer starts over i had a small splutter and a second or so of very lump idle...

Is something broke or wrong??

A little background info if it helps
-I have the tb coolant bypassed
-I dont have anything hooked up to the IACV pipe at the foot of the TB
-Aside from the multiplexor i have 2 other imediate codes come up for the IAT sensor High Voltage (P0113) & Evap purge Selenoid (p0443) i have removed the Evap selenoid & have no IAT plugged in so i was expecting them
-Before when the car was running i was getting TPS High Voltage and both primary and secondary o2 sensor codes too, not sure why as i hadnt enabled the emissions error checking (obd2)
-The black valve part that has the t peice coming off the side has been snapped, i dont have an air box on the car and therefor no sensor on the air box ... I have hooked the top hose over to the port inbetween 2nd & 3rd Injector and then i just tapped round where the t piece had snapped.

Please help i know this is probably above a lot of guys in here but im at a real loss now, let me know if you need more info too

Edit; i understand i need to loop the two pipes coming from the IACV, im also going to give the inside another clean through till it is spotless

i have trouble shot the MAP sensor Low Voltage according to the Acura mannual.

At position II

Step one 'check the MAP with a scan tool'

Is around 101 KPa shown; (I have no reading at all 0.0 KPa)

It then asks to test the two outside wires to check for around 5V... it is 5.07, so that is ok

It then asks 'check the MAP with a scan tool' again???

This time it says is 2KPa shown?

As in step 1 i have 0.0 KPa showing at position II

It then asks you to check continuity between the middle pin on the MAP plug and the body ground...

So i removed the 31pin A ecu plug

i put one probe on middle pin and one probe on a join from the chassis to the IM ground

Nothing!?

The soloution given is to try another ECU....

I dont have another PRA ecu, i just had the unit Kpro'd last week and its as new...

So now im confused again... i called my honda dealer and they are trying to be as profesional as ever and will not speculate untill i take the car to them...

Im having no luck on here so far too

Stuck in my mind is when i turn the engine on... the sensor reading in KPRO is 6550.3 kPA

Im thinking wtf am i to do now... spend money on new sensor to risk it or trailer it to the dealer (will cost a fair bit alone) Im begging for someone to have a read of my findings and help me out...seems im at a lost end

 

It sounds like you have a wiring problem & or ecu issue.
1. Check continuity on all of your sensors/plugs (map/tps).
You should have 5 volt power, ground & signal running from the sensor to the ecu for both tps & map sensors.
2. Fix all of your codes & proceed from there. (IAT)

If you can't figure it out, take it to a professional honda/acura tuner.
