How do I fix error code P2185?
How do I fix error code P2185?
What repairs can fix the P2185 code?
- A new ECT sensor.
- ECT connector or harness.
- Cooling system leak repair and fill.
- Thermostat replacement.
What are the symptoms of a bad ECT sensor?
What Signs May Signal Your Coolant Temperature Sensor May Be Failing?
- Poor Fuel Economy.
- Irregular Temperature Readings.
- Black Smoke from Your Exhaust.
- Your Engine is Overheating.
- Your Check Engine Light is On.
Where is the ECT sensor Honda?
Once the shield is off, look between the engine and the radiator and find the sensor. The Honda CRV Engine Coolant Temperature Sensor is located in the coolant pipe, below the air intake pipe and behind the right cylinder head and is integral with the ECT sensor.
What is the engine coolant temperature sensor?
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.
What does engine code P0128 mean?
Engine Coolant Temperature Below Thermostat Regulating Temperature
Code P0128 stands for Engine Coolant Temperature Below Thermostat Regulating Temperature. It means that the ECM/PCM has “noticed” that the engine coolant temperature is consistently running below thermostat regulating temperature. In other words, the engine is running cooler than it should.
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.
Will a bad ECT throw a code?
A failed (ECT) sensor can send a false signal to the computer; and throw off the fuel and timing calculations. It is not uncommon for the coolant temperature sensor to fail; and send a permanently cold signal to the computer. This will cause the computer to think the engine is cold, even when it is not.
How do you test a Honda ECT sensor?
Ohmmeter-Testing
- Start with a cold engine.
- Attach an ohmmeter across the sensor’s terminals.
- Measure the sensor’s resistance and record the reading.
- Reconnect the sensor wiring connector.
- Start and run the engine for two minutes, then shut the engine off.
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 I drive with a bad coolant temp sensor?
It is possible to drive a vehicle with a faulty coolant temperature sensor as the management system defaults to a static reading. A vehicle’s coolant sensor is a critical component used by the engine management system. It directly affects, cooling and fueling of the engine and therefore affects how the engine performs.
Where is the engine coolant sensor located?
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 causes the p2185 OBD-II trouble code?
What causes the P2185 code? This ECT (Engine Coolant Temperature) is one of two sensors the PCM uses to monitor the operating temperature of the engine. The PCM compares the voltage readings of sensor 1, sensor 2, and how long the motor has been running.
What does a code p2185 mean on a VW Beetle?
A code P2185 may mean that one or more of the following has happened: A bad connection at the #2 ECT sensor An open in the ground circuit between the #2 ECT sensor and the PCM A short in the voltage feed between the sensor and the PCM A bad temperature sensor (shorted internally)
How much does it cost to diagnose a p2185 Honda code?
The cost of diagnosing the P2185 HONDA code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
What does the p2185 code on the ECT sensor mean?
If the ECT sensor 2 output voltage is less than a set value when the engine coolant temperature is high, the PCM detects a malfunction and a DTC is stored. | Need more information with the P2185 code?
