The list of these parts includes mass airflow, coolant volume and temperature, cam and crank, cylinder head temp, and several other sensors. Just checked my e manual for the resistance on the sensor.

One of those numbers has to be wrong in my opinion. The 103 engine is the second engine of harley davidson that uses two cams to drive the valvetrain.

In high temp mode the engine rpms drops to 950 and the ecu goes to open loop mode to richen the fuel mixture to 12:1 in an attempt to cool the engine off. I debated arbitrarily replacing sensors, i think i'll start with this one.

Electrical system report receipt date: Give the engine some throttle and as soon as the engine rpms hits 1200, the ecu goes back to closed loop mode at 14.7:1 which is too lean, it drives engine temperature even higher and the engine stumbles.

When It Comes To Speed, This Engine Can Go Up To 100 To 120 Mph.

Fkg harley can't get anything right. When engine temperature reaches a predetermined point at idle, the eitms will turn off the rear cylinder fuel injector. A bad or failing cylinder head temperature sensor may cause performance issues such as a decrease in power, acceleration, and fuel economy.

Thankfully, Harley Seems To Have Fixed This Problem, And It’s Now In The Past.

I don't know which is correct. The other day i went over just about everything on my bike and pulled the boot off the head temp sensor to make sure it was still tightend in there. 7/8 cold and 3/8 hot is.
