neutral problem

Hi Peking duck

the sensor is perfectly plug to engine.i really dont know what cause this.

[pekingduck]

I recommend the two simple tests I described in my last post. That will tell us a lot, but may be only part of the problem.

Hi Max and Pekingduck

this is diagnostic result,need your advise[attachment=11890]

It would be nice if the actual code was listed, but.

Angle sensor of the throttle is the TPS (throttle position sensor)

Do this TPS reset first. Is easy and fast and may work: Turn ignition to on and wait for meters to sweep. DO NOT START ENGINE. Now open the throttle fully then close. Again open the throttle fully and close. Turn off ignition.

Or, you could have a TPS problem. Remove the connector and ensure the contacts are clean and in good condition on both the TPS and the connector. One of our members had this problem and had a crushed pin from the factory. If this doesn’t work, diagnnostic troubleshooting will be required. Note that the TPS sensor is not available as a separate item. If it turns out to be bad, the entire throttle body must be replaced. That is a pretty big and expensive job. We have not seen TPS failures yet. They tend to last a long time.

The O2 sensor fault is saying the O2 sensor is bad or it’s circuit is faulty. Ie, connector off or wiring problems.

If this bike is under warranty, why isn’t the dealer handling all this? If they don’t know how they should be on the phone to Honda tech support for well, support.

Popgun, it appears the bike is in a shop in India, possibly an independent shop and therefore no dealer or distributor assistance is available. I do not know if the Honda distrubutor in India has a Techline per se, and even still, it would rely on competent dealer techs as the first line. If the dealer doesn't have a shop manual, and be able to do the testing for the codes, it's a moot point.
rocketz, the bike has multiple electrical problems, seemingly unrelated. There is no magic bullet, no single cause for the faults. The codes retrieved point you to what Popgun described above, but they only affect the yellow engine light staying on.

The other faults, the lack of a green "N" indicator is a different circuits. As is the engine shutting down when put in gear. All require basic troubleshooting of their respective circuits, mainly connections. There may be bent pins or loose pin fits within the plastic connectors, or harness damage.

You need a shop manual to start testing continuity/resistance throughout the harness. These are not complex circuits, but the sheer number of faults on a "new" bike is suspicious. It didn't leave Japan like this.

PD, thanks for the info on his shop situation.

I agree that it appears he has a number of disparate electrical faults. Each one will need to traced and jumping all around won’t take care of the problems very well, as you pretty much indicated.

I wonder if the harness has been hacked into for some reason/mod or whatever.

Hi everyone,reporting some progress after i buy service manual for CB1100,i found wrong connection between sidestand and neutral switch.it has same connector.now i got N in dash.will update soon.anyway this bike is a brand new 0 Km on dash.never run.

[iamheero_imp]

Glad to hear you're making progress, hope you can ride soon!

[rocketz_imp]

making progress today,getting rid of 02 sensor error.this error cause of missed connection between left cover connectors to o2 connector on right cover.
but the TP sensor angle error low voltage (as shown above).what cause this? pin connector are good ECU are good,as this is a brand new bike.what can cause this failure? need advise
