What can cause a P0116 code?
What are the Possible Causes of the P0116 Code?
- Malfunctioning Engine Coolant Temperature Sensor.
- Faulty or corroded ECT wiring or connections.
- Engine overheating.
- Engine temperature below specification.
- An issue with the PCM, such as software in need of an update.
What does ECT sensor do?
A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off.
How is P0128 diagnosed?
The most common cause for P0128 is the engine coolant thermostat is stuck open. A simple way to diagnose this is to feel the radiator hose and monitor how hot the temperature of the coolant is when it starts flowing through the radiator hose.
How much does it cost to replace ECT sensor?
To replace the ECT sensor, you are going to pay, on average, $95-$140. How much you pay depends on the type of car you own and where you go for servicing. Each mechanic has their own rates, and they may be getting their parts from a variety of vendors, which can change how much the parts cost you.
Where is the ECT sensor located?
cylinder head
The ECT sensor is located in the left of the cylinder head and is connected to the Engine Coolant Temperature Sensor. Underneath the air intake pipe and behind the right cylinder head is where the Engine Coolant Temperature Sensor is located.
What does the code po128 mean?
The P0128 code means that the engine coolant is not getting warm enough, fast enough. In other words, there is a problem with the engine operating temperature not being reached within a certain amount of time. The Engine Control Module (ECM) determines this length of time based on ambient temperature.
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.
How do I know if my coolant sensor is bad?
Bad Coolant Temperature Sensor Symptoms
- Check Engine Light.
- Poor Mileage.
- Electrical Cooling Fans not coming on.
- Black Smoke from the Exhaust Pipe.
- Difficult Starting Condition.
- Engine Overheats.
- Poor Idling.
- Poor Engine performance.
Can low coolant cause P0128?
Low engine coolant can alter the engine running temperature enough to signal trouble code P0128. Your intake air temperature sensor, coolant temperature sensor and coolant fan could also signal this trouble code, so these should be inspected after you look over your thermostat and coolant level.
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.

What does code p0116 mean on a 2009 Toyota Corolla?
TOYOTA 2009 CODE P0116/P2616 Took the car to the dealer and the code is as follows: P0116 Coolant Temperature Circuit Rank P2616 ECM/PCM Engine Off. Found what the P0116 Code means but have not found the meaning of the rest “Rank P2616 ECM/PCM Engine Off”. This is a Toyota Corolla, Base Model, Automatic, 4 cyl, with 25,000 m…
What causes a p0116 code on an ECT sensor?
Potential causes of the P0116 code include: Missing or stuck-open thermostat Short or open on signal wire Short or open on ground wire Poor connections in wiring An example of an Engine Coolant Temperature ECT sensor If there are any other ECT sensor codes, diagnose them first. Using a scan tool, check the ECT reading.
