Pressure sensor error/reset question

My 2011 threw a dashboard error saying "Errors: Pressure."

I suspected this was the oil pressure sensor, so I changed it. The errors hasn't gone off, but the fact that it remains on even when the engine is not running makes me suspect that either you need to reset it (much like the service indicator) with the factory service computer, or that there is another error (short in wiring?)

Any thoughts as to what it could be?

Lastly, does anyone know what oil pressure readings should be and at what RPM?

Thanks

It may be one of the Manifold Absolute Pressure sensors, there is one for each throttle body. The parts catalog refers to them generically as "Sensor, Pressure." p/n is 55241571A for 2013. I don't have a spare parts catalog for 2011.

Bonadventure is correct. This error is with one of the absolute pressure sensors per the service manual. There are two sensors (one per throttle body). The vertical cylinder's sensor is attached to the back left side of the air box. You have to remove the tank to be able to get to it. The horizontal cylinder sensor is located near your GPS power supply behind the left air deflector (black plastic piece). The part number Bonadventure cited is the same for 2011. Look at page 49, item 6:

I would recommend first checking the connectors. Hit them with some connector cleaner and see if it fixes it. If not, you can look to replace them.

BTW, is the bike not running like shit? These are critical in proper fueling. Unplugged, you will run really rich to the point it isn't ridable.

I had a problem where one of my MP sensors was not working properly. However the sensor was still working, just giving out of range values. There were no errors shown or error codes recorded.

The bike ran OK still, but one cycling er was running very rich and the fuel consumption skyrocketed. Replaced the MP sensor for that cylinder, reset the calibration and everything was fine.

How did you determine it was giving out of range values if it never called attention to itself (i.e. never tripped a code).

The bike wasn't running quite right. One cylinder was running very rich (very sooted plug) and the bike was consuming a lot of fuel. After a lot of head scratching I swapped the MP sensors between cylinders. The rich running cylinder also swapped proving the sensor was the problem.

The ECU apparently didn't recognise any error as the sensor was still working, just sending wrong values. Unfortunately it appears the ECU is not smart enough to do any range checking.

A bit of old fashioned manual diagnostic work

It happened to me today. No performance issues..yet. Error went away.

My plan is to replace both sensors. I'd rather do it myself for $225 in parts rather than see if it's covered under extended warranty.

Any additional info / thoughts are appreciated.

Why? Just curious. A few months ago the extended warranty on my '12 covered heated grips, and both fork seals. $50 bucks total out of my pocket.

PS: Hows the riding in NGa been this weekend? Jealous as hell.

UPDATE: Disconnected front sensor. PRESSURE error remains. Must be rear.

It's 1.75 hour drive each way with no traffic. Plus deductible I'm sure. See update above. As I've narrowed it to one sensor, although it's the most difficult to reach, probably replace it and reassess.

Hit me up if you come down to ride the GAPS

Yeah, but your ride is down to Atlanta (I am assuming) and great roads at the start and finish.

At least one/two annual trips to Suches has been on my agenda since the early '90s. Going to try to get down there again before the cold weather comes back.
