Can ECT sensor cause no start?
Can ECT sensor cause no start?
The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.
What happens when the ECT sensor goes bad?
The signal from the (ECT) sensor tells the engine’s computer; when to apply extra fuel during a cold start. A faulty sensor can confuse the computer; keeping it from providing enough fuel. As a result, the engine may hesitate, stall, misfire or have poor engine performance. If the sensor sends a faulty “cold” reading, the engine will run rich.
What does ECT mean for an engine temperature sensor?
A typical (ECT) sensor is a Negative Temperature Coefficient (NTC) thermistor. Because, its electrical resistance, decreases when the temperature increases. This signal is then sent to the engines computer. So, changes can be made to the engine’s timing and fuel calculations; for optimal performance.
How is the ECT sensor connected to the PCM?
An (ECT) sensor is connected to the main computer (powertrain control module or (PCM). The (PCM) supplies a reference voltage (typically 5 Volt); and constantly monitors the (ECT) sensor signal. Based on this signal, the (PCM) adjusts the engines performance.
What should the ECT temperature be on my computer?
To check that the wiring and see if the computer is working okay, with scan tool still connected, look at the ECT temperature and unplug the connector from the ECT sensor. The temperature on the scan tool should read about −40° F.
When to turn on the fans at the ECT?
I have 5v at the ECT, The fans come on with the A/C and when jumping the pins on the ALDL port. I scanned the computer and it shows the coolant temperature above the fan enable temperature, no fans will run. The fans also do not run when it gets hot enough to trip the check gauges light.
