Personal Watercraft "PWC" Engine Sensors & Switches

In order to provide smooth engine operation and effective diagnostics, pretty much any modern personal watercraft relies on various engine sensors such as the crankshaft and throttle position sensors, temperature sensor, MAP sensor, etc. Mainly, they can be found in fuel-injected models, as the electronic module has to be aware of what's going on in the motor to provide the right air-fuel mixture. All of these parts have much in common with those found in cars and motorcycles, however, manufacturers tend to make any electronic components used in the marine environment more resistant to water and corrosion.

But still, most personal watercraft engine sensors and switches are subject to contamination and wear caused by their harsh working conditions. In particular, a TPS is a potentiometer having a sliding contact inside, and gradually, inner abrasion results in wrong signals. MAP and MAF sensors are exposed to continuous air flow that gradually makes them covered with dirt, yet cleaning them is often ineffective. Sometimes, tiny droplets of water getting onto wired connections also become the reason for different malfunctions. However, whatever troubles with sensors or switches you've faced, you will find the remedy on our virtual pages.
