Will a bad temperature sensor cause a misfire?
The coolant temperature sensor can also fail in a manner that causes it to send a permanently hot signal. This can cause the computer to incorrectly compensate for a lean signal, which can result in overheating, and even misfires or engine ping.
How long does it take to change a temperature sensor?
The actual process of replacing the coolant temperature sensor is extremely simple. However, the difficult work comes in the preparation of the cooling system – both before and after. Tip: This job should only be completed when the engine is cold and has not been running for a minimum of one hour.
What happens when a ECT sensor goes bad?
A faulty ECT sensor can send a false signal to the onboard computer, resulting in an incorrect air-fuel mixture. For example, a faulty sensor can send a signal indicating the engine is cold when it is not, and more fuel will heat the engine quickly.
Can a bad thermostat cause a temperature problem?
Bad gauges are one of the most common causes of problems. In our opinion no boater should be without an IR-Thermometer on board the boat at all times. You can shoot the temperature of the thermostat housing which should tell you whether the temperature that the gauge on the dash is reading is accurate or not.
What should the opening temperature of a water thermostat be?
Verify that the thermostat functions properly by inserting the thermostat into a pot of boiling water. Most thermostats will have the opening temperature stamped somewhere on the part, and should reach full stroke at approximately 20 degrees above the opening temperature.
What should the water temp be in a heat exchanger?
This means that if you were operating in 80 degree F water conditions, the water temperature exiting the heat exchanger and entering the exhaust risers should be in the range of 130 degrees F. The normal temperature tolerable to the touch is 140 degrees F.
