Error enabling closed loop kpro v4 (PRA)

[Spunkster]

I do not have that information as we do not have the PRA ECU's here and do not have the factory service information for it either. The error codes you have given are not even listed in any of the US manuals we have. All error codes are generated from the ECU, not the K-Pro. CPL may be able to get this info for you.

DTC P0132: Primary HO2S (Sensor 1) Circuit High Voltage


Reset the ECM (see page 11-4).
Start the engine. Hold the engine at 3,000 rpm (min-1) with no load (in Park or neutral) until the radiator fan comes on.
Check the primary HO2S (Sensor 1) output voltage with the scan tool.
Does the voltage stay at 0.9 V or more?

YES - Go to step 4.

NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the primary HO2S (Sensor 1) and at the ECM.


Turn the ignition switch OFF.
Disconnect the primary HO2S (Sensor 1) 4P connector.
Connect the primary HO2S (Sensor 1) 4P connector terminals No. 1 and No. 2 with a jumper wire.
PRIMARY HO2S (SENSOR 1) 4P CONNECTOR




Wire side of female terminals


Turn the ignition switch ON (II).
Check the primary HO2S (Sensor 1) output voltage with the scan tool.
Is there 0.9 V or more?

YES - Go to step 9.

NO - Replace the primary HO2S (Sensor 1).




Turn the ignition switch OFF.
Connect ECM connector terminals A6 and E4 with a jumper wire.

Turn the ignition switch ON (II).
Check the primary HO2S (Sensor 1) output voltage with the scan tool.
Is there 0.9 V or more?

YES - Substitute a known-good ECM and recheck (see page 11-5). If symptom/indication goes away, replace the original ECM.

NO - Repair open in the wire between the ECM (A6, E4) and the primary HO2S (Sensor 1).

Thanks for this check list.

I don't have narrowband, but sensor O2 and SO2 in the datalog measure 4.10 V (constant)

Maybe is this the incorrect value?
Now I want to understand how kpro read that value, but I don't have found it yet.

A question for Hondata: calibration with closed loop and external wideband and S02 disabled, however checks sensor O2 ??

[DonMizzi]

Hondata, I ask again two question that could be useful for my problem

- closed loop with wideband in PRA Ecu, needs a narrowband installed and properly working?

- The error P0132 is raised by 02 sensor that measures 4.10 V?


Finally, a technical information: If you not have a PRA to do the tests, who writes and tests the KManager code for this ECU?

Thanks
regards
Don

[Spunkster]

You do not need the narrowband if you run an after market wideband into the K-Pro analog input for closed loop.

We do not have the detailed technical information on P0132.

[DonMizzi]

Thanks for reply,

I read in the change log of 4.2.0 that you have removed P0132 Error in Open Loop. So you can manage this error?


Sorry if sometime I repeat the same question, but I'm slow to understand.
I ask again another info about my config, settings in this images are correct?

[DonMizzi]

On a winter night, God helped me

I have closed loop.

I used a simulated narrowband of my techedge in the A6 pin (AFR +)
So, the O2 sensor measures correctly a valid narrowband signal and the P0132 error disappeard.

That's amazing!

Now I have to check how it works at WOT, I've not yet tried.

and therefore I propose again some previous questions unanswered

1) Closed Loop, with Kpro4 and PRA, works at WOT?

2) In this image, "Closed Loop to Open Loop Switch - section TPS"
I cannot set values upper 99%
What it mean?
At WOT Kpro switches in Open Loop?

Acctualy, I don't undestand well this two table. I would like run always in closed loop. I think it's good setting or I'm wrong?




Thanks for the support
Don

[Spunkster]

It should allow you to run closed loop at WOt.

That table is for low RPM only and will not matter above that RPM.

[DonMizzi]

So, my last value (8000 RPM) is incorrect?

I saw that in the default MAP for PRA is 2687

I would change it?

[Spunkster]

I can't see any pictures. Leave the default values.

[DonMizzi]

Now you can see it?

Maybe I understand because you have not response at some question in older posts where there were images

[Spunkster]

No I cannot.

[DonMizzi]

Do I reset to default value?

This configuration works always closed loop, or, when I'm at WOT (100% TPS) switch to Open Loop?

In Kmanager documentation, Closed loop advanced, you write "Set 'Closed Loop Max TPS' tps values 100%" to enable closed loop with Kpro v4, but I cannot set it at 100%.
This is an error in documentation, or I make a mistake?




This is the default value

[Spunkster]

Are you trying to rely on the closed loop to safely run your vehicle without dyno tuning?

[DonMizzi]

I have done dyno tuning from an expert tuner.
But, with my "race" car, I want to have a more accurate and frequent control. I like it, I need it.

Also, my questions are mainly due to the fact, I love knowing things.
And I thank you for your availability

As you write, in my poor experience, I think that closed loop can give me a more safety on the track.
It's true?

I don't know yet modify fuel, cam, ignition and others tables
