How to clean the throttle body of a Honda CRV?
Start the car up and press the gas pedal to 3000rpm for 5 -10 mins (until both radiator fans comes on). 4. Release gas pedal and let it idle for 2 mins . Shut off engine . 5. Restart engine as per normal . Better throttle response , better fuel economy , better airflow . Please do this at your own risk .
Which is the best way to clean the throttle?
It is best to remove the throttle body and clean it fully on the front and rear of the bore. Once that occurs, the computer should be able to identify the positioning of the throttle plate and adjust the idle after driving for a while.
Why does the idle go up after cleaning the throttle body?
The idle is going to be high at first until the computer relearns the idle again. Cleaning the throttle body allowed more air to enter the engine, and the computer is compensating by adding more fuel.
Why did Honda change the throttle body for fuel injection?
When carmakers switched to fuel injection, the purpose of the throttle body change to operate more like an air valve, allowing more air into the intak manifold as you put the pedal to the metal. To provide air at idle, carmakers installed an idle air bypass valve that allowed air to flow around the closed throttle plate.

What’s the best way to clean a throttle plate?
Slowly open the throttle plate and begin cleaning by spraying the aerosol cleaner on a clean soft rag and wiping the solvent onto the throttle plate and throttle bore. NEVER spray the solvent directly onto the throttle plate. Also, never use abrasive scrubbing pads or brushes to remove the carbon buildup.
How do you remove the throttle on a Honda Accord?
On most vehicles, throttle body removal is required to access the IACV. The airbox and its accompanying hoses must first be removed, followed by the throttle cable and two coolant lines. Four 12mm bolts and nuts hold the throttle onto the intake, upon which the IACV can then be removed via two philips screws.
What causes carbon build up on Honda throttle body?
All electronic throttle bodies accumulate carbon buildup on the throttle plate and bore—the Honda throttle body is no exception. The carbon accumulates after the engine is shut down and is caused by hot oil and gas vapors rising to the top of the engine where they collect on the cooler throttle body.
How much does it cost to clean a Honda CRV throttle body?
Our certified mobile mechanics can come to your home or office 7 days a week between 7 AM and 9 PM. Honda CR-V Clean Throttle Body costs $164 on average. What is cleaning the throttle body all about? In order to run efficiently and smoothly, your vehicle needs a fuel mixture that is a perfect combination of air and gas.
How to relearn the Honda throttle body reset?
Reinstall the Honda throttle body using a new gasket and torque to specifications. Now that the carbon buildup is gone, you must “teach” the computer where the fully closed position is. This is called a Honda throttle body relearn or Honda throttle body reset.
When do you know your throttle body needs cleaning?
When your throttle body is operating below its normal effectiveness, one of the tell-tale signs is a poor or low idle. This includes stalling after coming to a stop, a low idle after starting, or stalling when the throttle is pressed down rapidly. Dirt causes airflow into the system to be turbulent and leads to a fluctuating idle speed.

The carbon accumulates after the engine is shut down and is caused by hot oil and gas vapors rising to the top of the engine where they collect on the cooler throttle body.
Can you clean the idle air control valve?
The idle air control valve will be partially cleaned when cleaning the throttle body. But, it is extremely difficult to fully clean the idle air control valve without removing it from the throttle body.
What’s the high idle after a carb cleaner?
High idle after throttle body cleaning throttles engine i… I cleaned my throttle body with carb cleaner about 5000 miles ago. My car used to idle at 800 rpm, but now, when the engine is cold, it idles at about 1500 rpm, going down to 800 as the engine warms up.
The idle is going to be high at first until the computer relearns the idle again. Cleaning the throttle body allowed more air to enter the engine, and the computer is compensating by adding more fuel.
The idle air control valve will be partially cleaned when cleaning the throttle body. But, it is extremely difficult to fully clean the idle air control valve without removing it from the throttle body.
What causes a Honda idle air control valve to stick?
A dirty idle air control valve (IACV), throttle body or PCV valve can cause rough idle, idle that is too low or high, dull throttle response or a car that doesn’t want to stay started once cranked. Carbon deposits build up on the butterfly valve and IACV solenoid, causing them to stick and function improperly.
How do you remove a throttle position sensor?
Part 1 of 2: Removing the throttle position sensor. Step 1: Locate the sensor. The throttle position sensor is mounted to the throttle body on top of the engine. Step 2: Disconnect the negative battery cable. Disconnect the negative battery cable and set it aside. Step 3: Remove the sensor electrical connector.
Where is the throttle position sensor on a Honda Accord?
Step 1: Locate the sensor. The throttle position sensor is mounted to the throttle body on top of the engine. Step 2: Disconnect the negative battery cable. Disconnect the negative battery cable and set it aside. Step 3: Remove the sensor electrical connector.
How much does it cost to replace a throttle body?
Regular maintenance can effectively prolong the life of the parts of the throttle body and you may not require a replacement for a long time. However, when the fixing of the problem requires a replacement, you will have to pay on average anywhere between $430 and as much as $550 for the parts only for most vehicles.
How does the throttle plate change in a Honda CRV?
The throttle plate angle changes as you step on or off the accelerator pedal. And of course, it’s the throttle position sensor’s job to measure it and report it to your 2.4L Honda CR-V’s fuel injection computer. This throttle plate angle information is critical for your CR-V’s fuel injection computer.
Is the throttle position sensor on a Honda CRV defective?
The throttle position sensor (TPS) on the 2002, 2003, and 2004 2.4L Honda CR-V is a simple 3 wire fuel system component that can be easily tested with just a multimeter (yup, no scan tool needed!). In this tutorial I will explain the TPS test that you need to perform to make sure that it is defective (or not).
How to test the TPS on a Honda CRV?
NOTE: You can find the 1997-2001 2.0L Honda CR-V TPS test here: How To Test The TPS (1997-2001 2.0L Honda CR-V). The throttle plate angle changes as you step on or off the accelerator pedal. And of course, it’s the throttle position sensor’s job to measure it and report it to your 2.4L Honda CR-V’s fuel injection computer.
How does the TPS work on a Honda Civic?
Honda Civic: How to Replace and Calibrate TPS. The throttle position sensor, or TPS, is used to control the actual throttle position relative to the amount of feedback it receives from the “Go Pedal.”. If this sensor falls out of calibration or fails, you may experience issues controlling the throttle of the car.
