No start and Fault code 14 after valve adjust

Hey Everybody, Will a fault code 14 (air pressure sensor) result in a no start situation?

A little background, I completed a valve adjustment this afternoon. Double checked all my work. When I completed I started getting fault code 14. Ran it thru the diagnostics and it says its ok but still no start and the code is still there. Am I supposes to erase it? Oh, and a put a new hose on it in case it had a leak. I dug back into it and pulled a plug and its definitely not getting any gas.

Im thinking about rechecking my timing again but that really doesn't relate to the fault code.

A little frustrated is all. If anybody has experienced this it would be nice to know if its truly the sensor or something else is going on.

Thanks

Damon

Do you hear the fuel pump prime when you turn the ignition on?

The code should clear once the problem is fixed. Probably missed a plug or mixed them somewhere.

The pump definitely kicks on. Going to pull the side panel tomorrow and make sure i didn't inadvertently pull a plug out near the ecu. Seems like the fuel injectors are not firing. I've rechecked all the plugs going into the throttle body.

My Bike is a 2012 model year with 24,272 miles. Is there possibly a fuse for the fuel injection system that could be broken? I did remove the battery to so the tray could be moved around for timing the cams.

There's 1 fuse for the FI system (10 amp) and another for throttle body 7.5 amp. If you hear the pump turn on when you turn the key on, I think your FI fuse is good.

Do you have spark?

I have started to pull everything back a part for a double check. This morning the code was gone until a attempted to crank then it came back. There was fuel in the intake and one of the plugs was wet. I havn't checked spark yet.

I had something like that on my second valve check. Found that I had not reconnected one of the harness plugs when putting it back together. Hooked it up and it fired right up.
I had even pulled a coil and was getting ready to check spark when I noticed it.

Fault 14 is 'Clogged or detached air pressure hose'. Have you checked it?

Carl, I've checked the hose and even replaced it thinking it had a pinhole. It was not clogged. However maybe there is something intermittently blocking the bottom of the sensor. Thanks for bringing that back up. It's going be a few hours before I get back to it. Family obligations.

I recently had a Fault Code 14 but the problem had nothing to do with an air leak. It had to do with a CCT failure when trying to start my 2012 with 52.2K. Another YST Rider had the same exact problem.

Hope yours is an air leak.

So this is a follow up. I went back and checked my cam timing. I was off. Thats my fault and got that straighten out. Hopefully I didn't cause some internal damage. The fault code is now gone. However, I still can't get it to start. I've got spark and fuel. It just won't grab. Any suggestions would be appreciated.

thanks

I suggest you hold the throttle partially open when you try and start her again.

Well, after some inspecting and checking, I decided to complete a compression test. 85psi on cylinder 1 and less than 50psi on cylinder 2. I messed up bad. preliminary reports indicate exhaust valves on cylinder 2 but would have to complete a leak down test to be sure. Where I went wrong was somehow I mixed up the timing mark on the intake cam with the "I" (that probably stands for Intake) thats also on there. So its pretty much my fault.

Your low compression readings might be from the automatic decompression action. At this point, since you can't do it any more harm, try push starting it, or get it to the nearest down hill, and try to bump start it. You "may" have flooded it by trying to start it earlier without success and now are experiencing the hard start syndrome. You can try the wide open throttle or removing the fuel pump fuse, and crank it over and see if that works, but NOTHING works as well as bump starting it, if you know how to do it.

Ok. Well, I'll admit that having the cam timing that far off that I might have bent some valves if this unit is an interference motor. I'll read the service manual. I do have a leak down tester and a visual probe I can use. It'll be tomorrow afternoon till I get to it.

Thanks everybody for your input. If I did bend some valves, I'll feel kind of embarrassed about it.

Is your Tenere still under extended warranty? The CCT can fail and cause the same.

EricV and I had CCT failures upon attempting to start the engine. Both of us had changed the oil / filter prior to the CCT failure. There is enough information on this forum to support a warranty repair.

By chance... did you notice any carbon buildup on the intake valves?

Double check the servo connection. I am one that made that mistake. You have to pay very close attention, the connector is identical to one of the coil connections.
