Hondata

Where can we buy one and what does it cost (roughly)?

We received the harness and it is the wrong one. It is a drive by wire harness.

Can we make it work if we run the TPS wires separately?

We used K24 harness plugs and wired the rest. I have a K20 (2002 to 2004) harness arriving tommorrow which we will then use.

We opened the ECU and started the engine (revving it up and down). There is no signal from the VTC pins going out of the ECU box (pins 1 & 23).

At the same time we know that the ECU is working in another car.

Earth was checked and we added additional earth wires to make sure.

That indicates a ...

Are we using the correct pins (1 & 23 on connector B)?

Can there be something else we can test which could cause this error?

We are now certain that:
- The VTC is fine (tried it on another car)
- The ECU appears to be good (loaded it on another car)
- We have the VTC connected to pins B1 & B23 ...

We are using the Kpro ECU with Hondata serial number 6474. Wiring of the VTC solinoid is onto pin 1 & 23. The engine is a K24 A2. The engine is a Japanese import model (not sure what year model)

We tried my ECU on another car, and it worked fine. We also installed my VTC solinoid on the other car, and got no error messages. The cam controller and cam angles operate as it should etc. That indicated that the ECU and VTC solinoid is ok, and that the problem should be wiring.

We followed the ...

We fixed both the P0563 & Lambda errors. So they can not cause the P0010 error.

We have now done the following:
- had an expert look at our wiring, and he found no problem. Similarly had AutoECU check our wiring with no problem found.
- Had the ECU bench checked by AutoECU (specialists in ECU repair), and they found no problem. I could not find a car to have the ECU plugged ...

Thank you - will check it out
