How did we estimate these prices?
Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for my ICP sensor replacement, and how much do those parts cost?

You should consult your vehicle repair guide and

owner’s manual

for detailed information about the ICP sensor. Here is a general overview of what you may need:

Injector control pressure sensor: The main part you’re going to replace is the sensor itself. The price will vary depending on the vehicle but you should be able to pick one up for between $75 and $250.

O-ring or gasket: If your new ICP sensor doesn’t come with a replacement o-ring, it’s a good idea to purchase a new one for the replacement. You should be able to find a new o-ring for less than $5.

Pigtail or electrical connector: If your ICP sensor’s electrical connector or pigtail is brittle or has exposed wires, you should replace it. A new one should cost between $10 and $30.

You can buy suspension lubrication parts for your car from auto parts stores like AutoZone, NAPA Auto Parts, and Advance Auto Parts, as well as online retailers such as Amazon and RockAuto.

Three brands we recommend for a replacement injector control pressure sensor are Motorcraft, ACDelco, and Standard Motor Products. If you also need to purchase new O-rings or gaskets, we suggest reputable brands like Fel-Pro, Victor Reinz, and Mahle. When it comes to purchasing a new pigtail or electrical sensor, three brands we recommend are Dorman, Standard Motor Products, and ACDelco. Keep in mind that the best options for your suspension lubrication parts will vary depending on your car’s year, make, and model.

Should I buy OEM or Aftermarket parts?

For most automotive repair jobs, original equipment manufacturer (OEM) parts are ideal—especially if you own a newer vehicle. This is because OEM parts are designed specifically to fit your car. They come with a manufacturer’s warranty and are made from high-quality, reliable materials.

The downside to OEM parts is they can be pricey and difficult to locate.

Aftermarket parts are a more affordable choice and are available in budget and premium options. While aftermarket parts can be a solid way to save some cash, you should remember to check the part number to ensure the replacement will fit your car.

Where can I buy the parts for my injector control pressure sensor replacement?

If you want to buy OEM replacement parts, you’ll have to visit your local dealership or contact an authorized parts distributor. You can find aftermarket parts at various auto parts stores—like AutoZone or O’Reilly Auto Parts—and online retailers like Amazon and RockAuto.

How will a mechanic replace my injector control pressure sensor?

These are the general steps your mechanic will follow to replace your ICP sensor:

Cut off the vehicle’s fuel supply—this may mean removing the fuel pump fuse or disconnecting the fuel pump cut-off switch

Remove the fuel system pressure by cranking the engine until it stalls

Locate the ICP sensor—depending on the car, it may be located on the cylinder head or engine block and may be behind or under other components

Unplug the sensor’s electrical connector

Remove the old sensor

Install the new sensor

Replace the electrical connection

Reconnect the fuel system supply

Turn the ignition key to the “ON” position and wait 10 to 15 seconds

Crank the engine and observe the sensor to check for leaks

Replace any remaining engine covers or components removed to access the sensor

Clear the check engine light if necessary

What happens if I don’t replace my ICP sensor?

If you don’t replace a faulty ICP sensor promptly, you risk developing the following problems:

Poor engine performance: If you have a faulty ICP sensor, the engine control unit (ECU) may have trouble adjusting the fuel injection timing and quantity. This can lead to issues like stalling, a rough idle, reduced power, and decreased fuel economy.

Increased emissions: If the ICP is causing the fuel injection system to function improperly, your engine may emit more harmful emissions. This may result in a failed emissions test and environmental pollution.

Check engine light: The check engine light will likely appear if you have a faulty ICP. If you ignore this light, you might not know about other vehicle problems before it’s too late.

Damage to other components: A bad ICP can lead to incorrect fuel delivery, which can put stress on other system parts. This can lead to premature damage.

Long-term engine damage: A faulty ICP can lead to long-term engine damage due to issues with the fuel injection system.

What is an injector control pressure sensor?

An injector control pressure sensor—also known as an injection control pressure sensor, ICP sensor, fuel rail pressure sensor, and fuel pressure regulator—is a component commonly found in cars with diesel engines. Its job is to monitor the fuel pressure in the high-pressure fuel rail that feeds the fuel injectors.

Instead of spark plugs, diesel engines rely on pressure and temperature to ignite the air/fuel mixture. The ICP sensor monitors the fuel pressure in the fuel rail and sends real-time data to the ECU. The ECU then makes adjustments to the timing and amount of fuel for increased efficiency and optimum performance.

When should I replace the ICP sensor on my car?

As there aren’t generally set replacement intervals for the ICP sensor, you should only need to replace yours if it goes bad. The most common symptoms of a faulty ICP sensor include:

Starting problems: One of the first signs of a bad ICP sensor is trouble starting the engine. If the sensor sends incorrect information to the ECU, the engine may not have the right fuel pressure for ignition. In this case, you may have to crank the engine several times to get it to start.

Engine performance issues: A bad sensor can disrupt the engine’s fuel mixture. This can lead to performance problems like misfires, stalling, decreased fuel efficiency, and a loss of power.

Check engine light: If your car’s computer detects a problem with the ICP sensor, the check engine light will likely illuminate. But remember that this light can appear for many reasons and you’ll need an onboard diagnostics (OBD) scan tool to diagnose the warning light.

Keep in mind: These issues may be the result of other problems, like a bad fuel filter, contaminated fuel tank, or electrical problems. The best way to get an accurate diagnosis is to visit a certified mechanic.

How often should I replace my ICP sensor?

There isn’t a set replacement interval for the ICP sensor—and for some drivers, the sensor may last for the lifetime of the car. That said, the ICP sensor is a wear-and-tear item and you’ll need to replace yours if it fails.

The most common symptoms of a bad injector control pressure sensor include a check engine light, difficulty starting the vehicle, and engine performance issues.

Can I replace my injector control pressure sensor myself?

You can replace your ICP sensor at home with the right know-how. The job requires mid-level mechanical experience and access to basic tools. And experienced DIYers should be able to handle the replacement with relative ease.

That said, if you’re uncomfortable handling the fuel system and electrical components, you should contact a professional mechanic.

FAQs

Will a bad ICP cause a no-start?

A bad ICP sensor can cause a no-start condition. If the sensor is malfunctioning and sending incorrect data to the ECU, the engine may not receive the right amount of fuel. This can result in difficulty starting the vehicle.

What does ICP do on a diesel engine?

The injector control pressure sensor monitors the fuel pressure in the fuel rail. The ECU uses this information to make adjustments to the fuel pressure, amount, and timing to optimize fuel efficiency, engine performance, and emissions.

How much does it cost to replace the ICP sensor?

The exact replacement cost for an ICP sensor will vary based on the vehicle and location, but you should expect the average price to fall around $410. We break that price down into $151 for parts and {X} for the mechanic’s $259.
