Can a bad ECT cause no start?

If you have starting problems and the ‘check engine’ light doesn’t come on, you may have a bad engine coolant temperature sensor (ECT). They’re quick and easy to replace.

Can a coolant temp sensor keep a car from starting?

The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.

How do you know if you have a bad ECT sensor?

If you notice more fluctuation in your engine temperature or it looks higher or lower than usual while you’re driving, it could be the engine coolant temperature sensor. In particular, if your engine doesn’t seem to be warming up as it typically does, you should have a mechanic take a look at your cooling system.

Can a bad coolant temp sensor cause rough idle?

A faulty coolant sensor that always reads cold may cause the fuel control system to run rich, pollute and waste fuel. A coolant sensor that always reads hot may cause cold driveability problems such as stalling, hesitation and rough idle. … This also affects engine performance and fuel economy.

Can you drive with a P0128 code?

You may drive your vehicle with a P0128 trouble code. You will not notice any issue except for maybe the temperature gauge never reaching normal levels, and possibly the Check Engine light being illuminated.

How do I test my ECT sensor?

Ohmmeter-Testing

Start with a cold engine. With the ignition off, disconnect the wiring connector from the (ECT) sensor. Attach an ohmmeter across the sensor’s terminals. Measure the sensor’s resistance and record the reading.

What causes coolant temperature sensor failure?

The engine may run in fail-safe mode:

Many Check Engine light codes related to the (ECT) sensor; could also be caused by other reasons. Such as a bad thermostat or issues with the cooling system; including even a leaking head gasket.

What does a coolant sensor do?

Can a bad ECT sensor cause overheating?

Engine Overheating

While sometimes a faulty sensor sends a permanent cold signal to the engine, it can also send a permanent hot signal. The computer will again miscalculate the signal and cause the engine to heat up instead of cooling it down.

Why is my engine coolant temperature light on?

The most common reason for the coolant light to become illuminated is simply that the coolant level is too low. There may be a floating sensor in your coolant tank that triggers the warning light when the level drops. … Low coolant levels are usually caused by leaks, either in the reservoir or somewhere in the lines.

Can you drive with a bad ect?

Faulty readings from the coolant temperature sensor can cause your car’s engine to miscalculate the fuel to air mixture within the engine. … If the amount of black smoke emitting from your car is excessive, then you should not drive your car and you should tow your vehicle to a mechanic.

How long does a coolant temperature sensor last?

about 100,000 miles

Often, the engine coolant temperature sensor must be replaced at about 100,000 miles. If you don’t properly maintain the engine cooling system, the sensor could fail much earlier.

How do you fix a coolant temperature sensor?

How long does it take to replace a coolant 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 sensors will cause a car not to start?

The most common sensors that will stop your car from starting include the camshaft sensor, the crankshaft sensor, the mass air flow (MAF) sensor, the manifold absolute pressure (MAP) sensor and the throttle position sensor.

Can you drive with a bad coolant temperature sensor?

It is possible to drive a vehicle with a faulty coolant temperature sensor as the management system defaults to a static reading. A vehicles coolant sensor is a critical component used by the engine management system. It directly effects, cooling and fueling of the engine and therefore effects how the engine performs.

What happens if fuel temperature sensor goes bad?

Decrease in power, acceleration and fuel efficiency

A faulty rail sensor may upset the air fuel ratio and cause the vehicle to experience performance issues such as a decrease in power, acceleration, and fuel efficiency, and in some cases may even experience stalling.

Why is my car reading hot but not overheating?

If you find that you’ve got a car running hot but not overheating there might be a few reasons: Clogged or damaged radiator. Low coolant level. Damaged water pump or thermostat.

How do I get air out of my cooling system?

Can a bad coolant temp sensor cause AC not to work?

Another symptom of a bad or failing ambient temperature sensor is inconsistent cooling. … If the ambient temperature sensor fails or is sending out an inconsistent signal, then the AC system may have trouble maintaining cool and comfortable cabin temperatures.

What should ECT be at idle?

Operating temps on most cars are between 185 to 220. With out looking it up I’d say the K24 shoould be right around 190-195. Although 202 is not bad.

Does the coolant temp sensor control the fan?

The sensor works by measuring the temperature that’s being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on-board control system. … As the control system receives the temperature from the CTS, it may trigger the cooling fan to either shut off or turn on.
