Where is the speed sensor located on a 20resa kohler genset

Hi,

if possible please check your speed sensors within your generator to make sure each is still functioning properly. Otherwise, you might have to replace the sensors before the code goes away.

Thank you.

Emergency shutdown operation is required when one of the above conditions occurs in diesel generator set.Diesel generating set itself has an emergency stop button, at this time, press the emergency stop button or quickly press the stop control handle of fuel injection pump to the stop position, the diesel generator will quickly cut off the load, and immediately close the throttle, while the red "emergency stop" light is on. Need to press the button again to delete the emergency stop signal. If there are serious faults or distribution faults, you can also press the button on the control panel, and the unit will stop immediately.

In fact, all faults always give operators some warning signal before spare parts break down or engine damage occurs. So the operators need to be smart, and notice alarm signals (sudden drop in oil pressure, abnormal sound, etc.) and immediately stopping the engine.
Emergency shutdown operation is different from normal shutdown operation.
Emergency shutdown operation.Once the operator finds that there is a serious fault or distribution fault in thediesel generating set, he can press the emergency stop button of the control panel to stop the unit immediately. If there is no special circumstances, we advise users not to stop the unit at will through the emergency stop button.

Here's a link to your speed sensor. Repair Guides Anti lock Brake System Wheel Speed Sensor Rotors toothed... Here's what it look's like. Vehicle Transmission Speed Sensor

Are you looking for the wheel speed sensor or the vehicle speed sensor?
The wheel speed sensor is located on the steering knuckles just behind the rotors.
The vehicle speed sensor is located on top of the transmission housing under the air filter bock housing.

If you need any more info or details on these sensors, let me know.
Hope this helps you.

The speedometer is in the instrument cluster. The speed sensor, I suspect this is your true question, is located in the transmission. If you look down, I know its difficult to see, where the dipstick tube goes into the transmission you will see a big electrical connector just to the right as you standing in front of the car. You will see the two rubber cooler hoses right above it. There will be a white plastic piece with a two wire connector right under those. That is the input speed sensor. This is not the part that needs to be replaced. The output speed sensors, the part that sends the speed signal to the computer, looks exactly like the input speed sensor but is located about 6-8" more to the right of the input speed sensor. Sometimes it is easier to spot from under the car.

If that sensor is bad it should flag a P0740 code in the pcm letting you know there are transmission codes stored in the TCM. A higher end scan tool (not a code reader) will be needed to get the codes from the TCM (transmission control module)

Hope that helps.

Your "Vehicle Speed Sensor" refers to two systems. In your situation it is your transmission mounted speed sensor. It is externally mounted and easy to replace. The other system is known as your "ABS sensors. They are located behind both front rotors and the rear one is on the drive-axle. But I don't think we need to get into that. If I can be anymore help, let me know, good luck.

No there is no way to do that unless you are a Kohler dealer, and have their service software, which is only available to dealers. It is called KOloader.

The code is specific to the engine speed sensor located on the side of the transmission near the output shaft. This device measures the output shaft rotation speed and allows the Electronic Control Unit (ECU - power control module) to program gear shifts as well as when to engage anti lock braking or traction control (by monitoring the output shaft speed sensor and comparing this with inputs from the wheel hub sensors). Locate the speed sensor connection and make sure the all the electrical contacts are free of dirt and corrosion. Remove the speed sensor and make sure that it looks physically OK and is clean, especially its tip. Check that all the wires are intact and that there is electrical continuity back to the ECU. The error code is consistent with an intermittent connection but if you suspect that the sensor itself is at fault it is not a very expensive item to replace.

Does the kohler generator have shut down sensors for low oil, exhaust temp and such? If so, check the sensors.


I checked the kohler website and noticed that one of the option was the siphon break. Does your genset has this? I had a similar problem like yours and my siphon break was blown. It was replaced.

What is more, do check the exhaust system of the generator and see if there is water flow.

When this happens, this usually means that your genset is not creating voltage. First thing I would do is disconnect your remote start wire from the genset, this will eliminate the start switch inside the RV. For a shorted remote start switch can cause you genset to shutdown. Second, place a volt meter at a spot where you will be able to read genset voltage. If no voltage is available and your voltage regulator is new, then the problem is with either the rotor or stator. The rotor is the easiest check. You need to reach the brushes. Take a resistance reading, which should be around 20 ohms. Clean the rings and make sure there is enough length on the brushes, at least over 1/2". Next, flash the fields using a 12Vdc battery. Use rubber gloves when doing this. Place the positive side to the ring closest to the bearing and negative goes to the back ring. This is done while genset is running so be careful with rotating parts. Have a volt meter on the output wires. Once you flash the fields the voltage should increase to over 50Vac. If it does then your stator is bad since you installed a new voltage regulator. If the voltage does not increase when flashing, then the rotor is bad.
