2005 e-tec

[fishead52]

Greetings.... This is my first post. I have a new PolarKraft 16.5 Kodiak V with a 50 Etec motor. The second time I took it out the motor would start perfectly but would not run past idle. The dealer checked it and said the computer showed a throttle position sensor error. They reset the code and it ran great for a few hours. Now it is doing the same thing. They told me that this can occur if someones shifts the throttle while the engine is turned off. They further stated that this info came from a evinrude rep. They also stated that resetting it is as simple as unplugging the cable for the sensor and plugging it back in. Just wondering if any of you experienced E-Tec guys have any further info on this. I haven't had then show me this connection yet, anyone want to take a stab at telling me where to look? Thanks a lot

On the in-line E-TEC models, the TP Sensor voltage must be below 0.78 volts when the engine is started, or it will not accelerate. This is a built-in safety feature.

I've seen this a few times, but normally on tiller-equipped engines - Is yours a tiller? It's real easy to do with a tiller-type throttle, if this is the case make sure the throttle is fully closed before starting.

It could happen to a remote control model if the throttle cable is misadjusted or if something with the throttle linkage is damaged.

There are 3 codes for TP sensors, which error code did it set? Unplugging and reconnecting the sensor will not clear the code or reset anything. I wouldn't go there...

Typical dead-idle voltage for the 40 thru 90 E-TEC is about 0.50 volts. The next time your dealer looks at this, ask him to check the TP voltage using the diagnostic program. With the throttle fully closed, the reading should be close to 0.5 volts.

Thanks for the response.....not sure the exact error code, I can tell you it is a remote, not tiller. I have a young grand son and a teen age son. I thought maybe they were playing with the throttle. Usually it will throttle up if I press the shift bypass button on the throttle control, like you would do for the winterization process. I would just like to chase this thing to the final problem...so I can have some peace. The motor is great on gas and oil consumption, and has excellent power to weight ratio. Thanks for your response

Just a follow up on the throttle position sensor issue I had going on with the 50 e-tec. The dealer checked all the voltages and did some resistance testing through the sensor. It had set two codes for the sensor 12 and 13 I believe. On advice from Tech support they installed an upgraded sensor which in and of itself did not fix the problem. A couple of the techs put there heads together and found a bent pin in the cable connection to the sensor. It was probably like that since assembly.
I have put three or four hours on it with some stopping and starting. It is doing great. Thanks for the info again!!! ...Terry from Indiana
