What happens to the engine temp sensor on a Harley Davidson?
Also with the sensor removed the engine idle will remain high, in cold idle mode. Ahh sensors , ya gotta love failing sensors on ALL the newer Harley’s . Sometimes newer doesn’t equate to better , especially when it comes to Harley’s !
What does the Check Engine light on the coolant temperature sensor do?
Check Engine Light comes on The coolant temperature sensor, also known as the coolant temperature switch, is an engine management system sensor that is used to monitor the temperature of the engine’s coolant. Most coolant temperature sensors operate using electrical resistance to measure the temperature of the coolant.
Can a faulty air temperature sensor cause idle hiccups?
Idle is also one of these conditions when the engine is susceptible to the right air-fuel mixture. This is also a condition when you can feel the faulty air intake temperature sensor’s slightly faulty air-fuel mixture. If you experience some small hiccups on idle, it can be a faulty IAT sensor.
What should the idle temperature be on a Harley Davidson?
The cylinder will suck in air to cool the engine. Engine temperature exceeds 284 °F 140 °C (all except configuration J and L) or 324 °F 162 °C When the engine is in EITMS operation, you may notice a difference in idle cadence. Additionally, there may be a unique exhaust odor. These are both considered to be normal conditions.
Also with the sensor removed the engine idle will remain high, in cold idle mode. Ahh sensors , ya gotta love failing sensors on ALL the newer Harley’s . Sometimes newer doesn’t equate to better , especially when it comes to Harley’s !
What should I do if my engine temp sensor is not working?
Locate the sensor away from the engine heat and start the engine and run it untill it’s hot. If the engine doesn’t act up in the same amount of time it’s a good bet the sensor is failing. I {Heart} Hookers.
Idle is also one of these conditions when the engine is susceptible to the right air-fuel mixture. This is also a condition when you can feel the faulty air intake temperature sensor’s slightly faulty air-fuel mixture. If you experience some small hiccups on idle, it can be a faulty IAT sensor.
