Honda CRV Engine Coolant Temp Sensor Replacement Cost
An overheating engine can cause catastrophic damage if you ignore the warning signs.
Typically, the average coolant temp sensor cost crv owners pay ranges between $150 and $300 at a standard repair facility.
If you choose to use an independent shop, the honda crv coolant sensor shop price normally falls toward the lower end of that spectrum.
Dealerships will consistently charge premium rates for both diagnostic scans and original equipment parts.
Understanding the exact honda crv ect sensor labor price will help you negotiate a fair rate with your local mechanic.
Labor generally takes about one hour, resulting in a labor charge of $90 to $180 depending on your location.
The OEM sensor itself is relatively inexpensive, usually costing between $35 and $70.
If you own an older model, you might wonder about the used honda crv engine coolant temp sensor replacement cost, but we strongly advise against buying used electrical sensors.
A brand-new sensor ensures accurate readings and protects your vehicle from expensive engine melt-downs.
For those trying to figure out how much to replace coolant sensor honda crv models on a budget, doing it yourself is the absolute best option.
Below is a practical guide that will walk you through the entire process step by step.
| Expense Component | Independent Shop Estimate | Dealership Estimate |
|---|---|---|
| OEM Part Cost | $35 – $60 | $75 – $110 |
| Labor Charges | $80 – $120 | $150 – $220 |
| Total Replacement Cost | $115 – $180 | $225 – $330 |
Prerequisites and Tools Needed
Before beginning your repair project, gather all the necessary tools and supplies.
You will need a standard socket set, including a 10mm socket and a 19mm deep socket.
Purchase a new Engine Coolant Temperature (ECT) sensor and a fresh bottle of Honda Type 2 blue coolant.
Keep a clean rag, a drain pan, and safety equipment nearby.
The entire replacement process should take less than an hour, making it an excellent opportunity for saving hard-earned money.
Step 1: Cool Down and Safety Preparation
Never work on a hot cooling system because hot pressurized fluid can cause severe, painful burns.
Ensure your Honda CR-V has been sitting turned off for at least two hours.
Disconnect the negative battery cable to prevent any accidental electrical short circuits.
Wear protective gloves and safety glasses to keep toxic chemicals off your skin and out of your eyes.
Step 2: Locate the Engine Coolant Temperature Sensor
Open the hood and find the sensor, which is usually located on the cylinder head housing near the thermostat wrapper.
On most 2.4L engines, the sensor sits on the back or side of the engine block.
Refer to your owner’s manual to confirm the exact location of the sensor on your specific model year.
Gently squeeze the plastic release tab on the wiring harness and pull it away from the sensor.
Step 3: Remove the Old Sensor
Place a clean drain pan directly beneath the engine area to catch any escaping fluid.
Use a deep socket to loosen the old sensor by turning it counterclockwise.
Prepare the new sensor with its sealing washer beforehand to prevent excessive coolant loss.
Carefully unscrew the old sensor by hand and quickly block the opening with your finger or a clean rag.
Step 4: Install the New ECT Sensor
Thread the new sensor into the cylinder head by hand to avoid cross-threading the soft metal.
Tighten the sensor using your socket wrench until it is snug.
The standard torque specification for this sensor is approximately 12 foot-pounds.
Reattach the plastic wiring harness connector until you hear a distinct clicking sound.
Step 5: Top Off Fluid and Bleed the System
Fill the radiator and coolant reservoir with fresh Honda Type 2 blue coolant.
Leave the radiator cap off and start the engine to let it reach normal operating temperature.
Watch for air bubbles rising to the surface, which indicates that air is successfully escaping the cooling loops.
Once the radiator fan cycles twice, replace the radiator cap securely and clean up any spilled fluid.

Understanding Diagnostic Trouble Codes P0117 and P0118
When your engine control module detects a problem with the temperature readings, it immediately illuminates the check engine light.
You will typically pull diagnostic trouble codes like honda crv code p0117 p0118 from the OBD-II port.
A failed sensor will trigger a persistent honda crv code p0117 p0118 sensor error on your scanner.
Code P0117 indicates that the voltage output from the sensor is abnormally low, implying the engine is running extremely hot.
Conversely, code P0118 indicates a high voltage signal, which means the circuit is open or the sensor has failed completely.
To confirm whether the sensor itself is the issue, you should execute a quick honda crv coolant sensor test guide process using a digital multimeter.
Performing a thorough honda crv coolant sensor test will tell you if the wiring is damaged or if the sensor is dead.
Measuring the resistance of the sensor across different temperatures will prove if the internal thermistor is broken.
This simple test can prevent you from purchasing new parts when a damaged wiring harness is actually to blame.
Common Issues on the 1.5L Turbo and 2.4L Engines
Different generations of the CR-V feature distinct engine designs that impact cooling dynamics.
The newer 1.5L turbocharged engines are highly sensitive to temperature fluctuations and require precise coolant regulation.
A faulty sensor on these engines can cause fuel injection issues, poor idle performance, and reduced fuel economy.
Older 2.4L naturally aspirated engines are incredibly robust, but their plastic coolant housings tend to degrade and leak over time.
According to the CR-V Owners Club community, ignoring a faulty sensor can lead to head gasket failures on both engine types.
Always replace the sensor at the first sign of erratic temperature gauge behavior to protect your investment.
Preventative Maintenance and Cost-Saving Strategies
Regular cooling system maintenance is the most effective way to prevent premature sensor failure.
Performing a scheduled honda crv coolant flush removes corrosive contaminants that degrade internal sensor components.
Over time, depleted coolant loses its protective properties and allows scale build-up on the sensor tip.
If you are replacing the sensor, you should also consider a honda crv thermostat replacement at the exact same time.
These two parts work closely together to control your engine temperatures, and replacing them simultaneously saves on labor costs.
Understanding the average coolant temp sensor cost crv drivers typically encounter allows you to evaluate mechanical quotes accurately.
Buying high-quality OEM Honda parts ensures maximum compatibility and prevents premature part failure down the road.
Avoid These Common DIY Mistakes
Many DIY enthusiasts accidentally strip the threads on the cylinder head by over-tightening the sensor.
The aluminum housing is soft and can crack easily under excessive pressure.
Another frequent error is failing to bleed the air out of the cooling system after installation.
Trapped air pockets will cause erratic sensor readings and localized engine hot spots.
Never reuse the old crush washer, as it will almost certainly cause a slow, frustrating leak later on.
Knowing how much to replace coolant sensor honda crv components yourself can protect you from overpaying.
Finally, always ensure the engine is completely cold before removing any cooling components to avoid catastrophic injury.
Frequently Asked Questions
Yes, a failing sensor can severely hurt your fuel economy.
The engine computer relies on temperature data to calculate the correct fuel-to-air ratio.
If the sensor falsely reports a cold engine, the computer will inject excess fuel into the cylinders.
This running condition wastes gasoline and can eventually damage your catalytic converter.
You should avoid driving your vehicle once you detect a faulty sensor.
Without accurate temperature readings, you will have no warning if your engine begins to overheat.
Severe overheating can warp the cylinder head and destroy your entire engine block.
We highly recommend addressing this sensor issue immediately to prevent unnecessary financial disaster.
Replacing the sensor yourself using OEM parts will not void your vehicle warranty.
Under the Magnuson-Moss Warranty Act, manufacturers cannot void your warranty simply for performing your own maintenance.
However, any damage caused by improper installation or aftermarket parts will not be covered.
Always keep your receipts and document your repair work carefully to maintain your coverage records.
