Any input would help, thanx. We just need to get whatever is wrong fixed by next weekend. We checked the throttle cable and it was kinda pulled out of the carb, we fixed that and now it runs great. For some reason the bike doesn't accelerate as smooth and hesitates as well as idles rough. It's definately not the carb, TPS, or computer. or will by farting around like this create a problem and burn up the CDI? Potentiometers are variable resistors that have a spinning contact, sometimes known as a wiper, and a resistance substance. I had the TPS eliminator on mine. How Much Does It Cost To Replace An Alternator. Knob? But hey I am no expert. The gas tank must be removed, you must be able to get the bike running for several minutes - yes w/o a gas tank, the carb has to be removed to a position to adj the TPS before finding the magic spot to tighten - it literally is hanging on. Curious how you adjusted the TPS Sensor? The throttle position sensor measures the position of the throttle blade. You will notice it on a dyno, but probably not your butt dyno. Content on bluetraxx.com is generated by its users. Gasoline that has not been burned escapes into the exhaust system due to a poor fuel-to-air ratio. Each time the ignition is started, the ECU sends a 5V reference signal to each of its analog sensors. The cars throttle body wont function if the throttle position sensor malfunctions. Content on bluetraxx.com is generated by its users. stopped for a few minutes and wouldnt restart. You can check it with an OBD2 scanner. The engine wont start if it doesnt get air.

I should re-phrase my prevous post.. the bike will not idle (ever). The YFZ ignition actually has two timing curves, a partial throttle curve and a full throttle curve. Mine is still under warranty and it is in the shop for an axle replacement. At WOT the spark timing is retarded in relation to the spark timing at half or lower throttle. One is a battery problem. my yfz runs very poor on the buttom when reving up. so i finally got time to test my tps again and the DCV settings doesn't do anything. It ont stay in time, you got lucky it only jumped a tooth or 2, next time it might mean catastrophic engine failure. Since it measures the angle of the throttle body valve, the throttle position sensor is situated on the throttle body. The Fora platform includes forum software by XenForo. The throttle position determines how much air enters the intake manifold of an engine; when it is wide open, more air enters; when it is virtually closed, less air enters. If working with electricity makes you uneasy, avoid attempting this since it might be harmful to remove the incorrect fuse or cable from your battery. Ill demonstrate how to identify and fix a throttle body in a car or truck.

Disconnecting it does no harm to the system, but it does disable the ability to map ignition timing according to both engine speed and throttle position, so the CDI rolls over to a two dimensional map based on the assumption of full throttle and uses engine speed as its sole reference. yfzcentral.com is an independent Yamaha enthusiast website owned and operated by VerticalScope Inc. Using an automotive diagnostic tool or taking your car to a professional will help you identify the root of the problem. The throttle position sensor, which is connected to the throttle body, measures the amount of air being sucked into the engine at any one time as well as the throttle position. If there is not enough air or gasoline, the vehicle will not accelerate quickly enough. Sensors with fewer applications, like the 4-wire and 5-wire TPS, have internal switches that report idle or wide-open throttle settings. Not so here. What other electronics could have been damaged? i have adjusted the "knob" , unplugged the sensor no change in anything. The third terminal completes the electrical circuit (ground). Some say they have cured the problem with a vortex ignition. Turns out the throttle plate, aka slide, can go in two ways. Jerking or hesitation might be indicators of a bad throttle position sensor.

Copyright 2023 Mechanic Base. Always check the connections for corrosion whenever an electrical connector, such as the TPS connector, is removed. I guess it wasnt the PCM, we swapped it with another one and no changes. Clearing any associated error codes and maybe reprogramming the new TPS modules software to function with other engine control software is also necessary when replacing the TPS. Throttle position sensors need at least three wires for their electrical setup: one for the ground, one for the returning voltage, and one for the reference voltage. The throttle body may not appear to be in the worst shape from the front depending on how clogged it is, but the side may reveal otherwise. 3. Symptoms of bad throttle valve position sensor in your car. Some modern cars feature a special limp mode that enables them to run at a very low speed when the engine fails. the engine's computer has built-in logic that monitors the tps feedback to make sure it matches up with information sent by other engine sensors.

There is two seperate ignition curves. I had to just stick the torq bit in there and use a damn open end wrench to twist, which sucked too cause I didnt have any down pressure on the bolt head. The location of the throttle valve on the throttle body is determined by a throttle position sensor. We sometimes link to products in our posts and some of these links may be affiliate links this means should you purchase through the link, we earn commissions. For the engine to know how much acceleration you want and how much you give, it needs to measure the throttle bodys angle to match it with the fuel injection. For anyone thinking of attempting to do this, save yourselves a lot of frustration and mark the sensor and the carb with a precise notch for the factory setting. The check engine light by Wikiuser100000 / CC BY-SA 3.0. Poor Fuel Economy #5. The reference voltage enters one of the TPSs terminals, travels through the resistive component of the potentiometer, and then exits via a different terminal to return to the ECU. 02 Blue Kenz 686 with everything chrome or polished. Double check the timing and make sure that all the marks line up right. They say that the stock ignition has a problem determining the correct timing due to the TPS and the ignition not knowing whether to advance or retard.
