I have a 2010 Honda NT700VABS with 4100 miles. Recently, after about riding for 1 mile, it started to hesitate and the engine light came on first flashing and then steady. I stopped the engine and after 15 mins, the engine started without trouble but the MIL (Malfunction Indicator Lamp PGM) stayed on. Subsequently, the bike ran fine but still showed the Malfunction. I took the bike to the Honda dealer.The honda dealer said that the diagnostic check indicated Code 4, TPS (Throttle Positioning Sensor) malfunction. I can't find the TPS on any part list. Where is this sensor? What is its part number? Can it just be replaced or do you have to replace the entire throttle body? How can you test the sensor to see if the imput to the sensor is faulty?A friend suggests the following test:The TPS typically is just a potentiometer that converts the the throttle plate's position to a resistance that the bike's computer can read and uses to adjust the fuel flow to the throttle body. First find where the wires connect to the throttle body and check the connector to make sure it is making a good connection. Then trace the wires back to the bike's computer and make sure that connection is good as well. Next disconnect the connection to the computer and use an ohmmeter to measure the resistance to the TPS and its wiring back to the computer. You should be able to vary the resistance reading by twisting the throttle. If it reads an open circuit, the problem is either in the wiring or the TPS. Go to the TPS and measure the TPS resistance with the wires disconnected.Does the above make sense?The honda dealer wants to replace the entire throttle body for $950.00. Please advise.Thank You
Hello how are you
The info you were given is correct. The TPS comes only with the throttle body assy.
Given the age and milage of the bike i can offer you some additional advise
Honda is usually very helpful when it comes to customer service. I suggest you express your disappointment with your bike and this components failure so early in the bikes life. Be sure to mention to them how dedicated you have been to honda and its products. I'm sure you have owned many honda bikes in the past, a honda car or van, honda lawnmower, and even your honda outboard on your boat.
The service manager can usually mention this to his rep and in most cases they will (good will) or pay for the part and only make you pay labor fees. If he or she is unwilling or tells you no, ask for the number for customer service and let them know how you feel yourself.
Fyi, do not mention lawyers or lawsuit. They will shut you right dowm
I see you have had a chance to review my answer, if you have further questions let me know.
You did not address the question of how can you test the sensor to see if the imput to the sensor is faulty. I also provided a possible procedure for this test and asked if it made sense.
I am not satisfied with the answer. You did not answer the question "How can you test the sensor to see if the imput to the sensor is faulty? You did not answer the question " Does the above (test procedure) make any sense? Therefore, please refund my money.
