Kpro V4/Kmanager help needed. So I have an issue where the ecu will throw a P0113 IAT code when I plug in the boost control solenoid (MAC 4port 46A-AA1-JDBA-1BA). I have 1 wire to +12 ignition and other wire to B21 (B plug, pin 21) of ECU. I verified there's no short in the wiring as well. This P0113 code is repeatable by plugging in the boost control solenoid, unplug and code goes away, plug and code returns. Using a meter I see about 7volts (negative) coming from B21 (solenoid isn't pluged in). Seems the issue is +12v feeding back into B21 when ign is on and solenoid is plugged in. Is the solenoid bad? It's a brand new solenoid and I tested the solenoid with 12v and hear it click, practically no resistance/ohm (assuming its suppose to be this way since its just a coil).

Also is there a way to test output like the s300?

TIA

It sounds like you have it connected to the wrong pins. You may want to verify at: http://www.hondata.com/help/kmanager/ecuconnectors.htm

I have a prb-A03 ecu, and using pin b21.. I'm assuming that link references the same ecu?

Post a picture of how you have it connected, showing the pin at the connector.

It's the wire with blue tape on it... do I have it in the right pin? The original wire that was there was a different color, I depinned and put that wire in its place.

That is the correct pin, but where is it going from there?

What vehicle is this in?

This is a K swap Toyota MR2.. the wire w/tape goes to boost control solenoid.. the other wire at boost control solenoid (red paint on it) goes to +12volts ignition with 5amp fuse.

I would recommend that you try the ECU on a known working vehicle. If it works as it should, then you have a wiring problem that needs to be resolved.

Is there a way to test the outputs on Kmanager? Like how the s300 can.

No there isn't, it must be activated based on the parameters set for boost control.
