What You'll Learn
Fuel Injector Correction Reset
The Chevrolet Cruze is fitted with a range of fuel injectors, with some of the most popular brands being ACDelco and Bosch. Fuel injectors on the Chevrolet Cruze can be replaced and reset by the user, and there are several online forums dedicated to this process.
One forum user detailed their experience of performing a fuel injector correction reset on their Chevrolet Cruze. They stated that they were able to clear the SES and, after driving for around 20 miles, the light did not reappear. However, they did note that they were unsure of the cause of the issue, and speculated that they might have a leaky injector.
Another forum user provided a step-by-step guide to performing a fuel injector correction reset:
- Stop the engine and connect INSITE service software to the ECM.
- Select "Advanced ECM Data", "High-Pressure Common Rail Injector Settings", and "New Barcode".
- Enter the injector correction code for the corresponding cylinder and select "Apply".
- Follow the procedure prompts until you see a confirmation message.
- After setting the injector barcode, enter "Advanced ECM Data" and "Injector Reset".
- Select the cylinder number of the replaced fuel injector and click "Reset".
- Follow the procedure prompts until you see a confirmation message in the status bar.
It is important to note that resetting the ECM after installing new injectors is not always necessary, as the O2 sensor will read the air/fuel ratio and provide this information to the ECM, which will then pulse the injectors with the correct amount of fuel. However, some users have reported improved mileage after resetting the ECM.

Fuel Injector Timing Learn
Fuel injectors are fuel metering devices that spray atomized droplets of fuel in a specific pattern into the engine's intake manifold or directly into the combustion chamber. The injector has a solenoid and valve within, and the operation, or pulsing, of the solenoid is controlled by the powertrain control module (PCM). The PCM controls the solenoid's "on" time to maintain an optimized air-fuel ratio while the engine load and operating conditions are subject to change.
- Verify that there are no aftermarket performance-enhancing devices installed on the vehicle.
- Perform the Fuel Injector Correction Reset for the appropriate fuel injector.
- Perform the Crankshaft Position Reluctor Wheel Learn.
- Perform the Fuel Injector Timing Learn to verify that the DTC does not set. If the DTC is set, refer to Circuit/System Testing. If the DTC is not set, continue with the next step.
- Perform an engine compression test.
- If the engine compression is not within specification, repair as necessary. If the engine compression is within specification, replace the appropriate Q17 Fuel Injector.
It is important to note that fuel injectors should not leak fuel into the intake manifold when the car is turned off. If there is an external leak from a broken or malfunctioning injector, do not start the car due to the fire hazard. If the injector is known to be malfunctioning, it can cause issues such as engine misfires, excessive emissions, or an overload and overheating of the catalytic converter.
There are several options available for purchasing fuel injectors for the Chevrolet Cruze, with prices starting from $34.99.

Fuel Injector Replacement Costs
The fuel injection process helps to provide maximum power while minimising fuel consumption and reducing pollution. Fuel injectors help reduce emissions by producing a finer fuel droplet spray that burns more efficiently. Electronic fuel injectors are more reliable and efficient than their older counterparts, making them a popular choice.
The cost of replacing fuel injectors can vary depending on several factors. The make and model of your vehicle, its age, the severity of the issue, and your location can all play a role in determining the price. The cost of the parts and labour for the replacement can range from $150 to $400, with the total replacement cost ranging from $300 to $900. Some individual fuel injectors can be purchased for under $40 each, while others may cost several hundred dollars apiece.
For example, a 2019 Toyota Yaris owner was quoted $2150+tax for replacing all four fuel injectors, which they considered too expensive. They were able to find OEM injectors for around $800 online, and a FelPro gasket for under $40.
It is important to keep in mind that cutting corners on parts or labour can lead to bigger problems and more expenses in the future. Investing in high-quality parts and ensuring proper installation, whether by a professional or oneself, is often the wisest decision when replacing fuel injectors.
Some signs that indicate the need for fuel injector replacement include:
- Increased fuel consumption
- Decreased fuel economy
- Decreased engine performance
- Leaking injectors
- Malfunctioning injectors
To identify if your fuel injectors need replacement, you can test for fuel pressure and flow using a multimeter or voltage test to check for current.
Another option to consider is purchasing refurbished or remanufactured fuel injectors instead of brand new ones. These options can be just as reliable and effective but at a lower cost. Additionally, routine maintenance and the use of high-quality fuel can prolong the life of your injectors and potentially prevent the need for replacement.

Fuel Injector Removal
The Chevrolet Cruze is a car manufactured by General Motors that has been in production since 2001. While I am unable to confirm the type of fuel injectors the Chevrolet Cruze has, I have found some information on how to remove them.
Fuel injectors can be removed from a car engine by using a screwdriver to pry on the retainer, sliding it off to the side, and then removing the injector from the rail. However, this process can vary depending on the specific model of the Chevrolet Cruze. For example, for 2015 and earlier models, the following steps should be taken:
- Disconnect the negative battery terminal and remove the engine cover if present.
- Relieve the fuel system pressure and then remove the air intake duct and air filter housing.
- Release the quick-connect fuel line fitting at the fuel rail and disconnect the EVAP purge line from the intake manifold.
- Unclip electrical connectors from the fuel injectors and MAP sensor.
- Remove the fuel rail mounting bolts as well as the ground strap (if equipped).
- Remove the fuel rail and injectors as a single assembly, ensuring no O-rings are left inside the injector holes.
For 2016 and later models, the process is slightly different:
- Relieve the fuel system pressure and disconnect the negative battery remote terminal.
- Remove the oil filler cap and engine cover fasteners, then lift up the engine cover with the valve cover insulator, reinstalling the oil filler cap if needed.
- Take out the ignition coils and charge air cooler outlet hose.
- Disconnect the harness connectors from both the fuel rail and camshaft position sensor, moving the wiring harness aside.
- Remove the sound insulator around the high-pressure pump body of the fuel pump area.
- Use a flare-nut wrench to unscrew the intermediate high-pressure line fittings between where they enter or exit from their respective cylinders' heads to access the bracket bolt for removal.
It is important to note that special tools, such as demounting screws and support tools, may be required for the removal of fuel injectors. Additionally, it is recommended to replace the old O-rings on each injector with new ones and to lubricate the new O-rings with clean engine oil before installing them. Once the injectors are replaced, the fuel rail mounting bolts should be tightened and the engine should be started to check for fuel leaks.

Fuel Injector Seals
Fuel injectors are fuel metering devices that spray atomized droplets of fuel in a specific pattern into the engine’s intake manifold or directly into the combustion chamber. The injector has a solenoid and valve within, and the operation, or pulsing, of the solenoid is controlled by the powertrain control module (PCM). The PCM controls the solenoid’s “on” time to keep the air-fuel ratio optimized while the engine load and operating conditions constantly change.
Fuel injectors are usually connected to a fuel rail located on top of the engine. This fuel rail is supplied with fuel under pressure from the fuel pump located in the fuel tank. The injector is held very firmly in a finely polished bore in the fuel rail by an O-ring seal. This O-ring fits very tightly to prevent fuel leaks.
When servicing or replacing a fuel injector, the injector is removed from the fuel rail, taking care to not allow any debris to enter the exposed openings. A new O-ring is then used to re-insert the serviced or replaced injector into the fuel rail, using engine oil on the O-ring to prevent damage. The fuel rail is then re-installed, and the supply and return lines are re-connected.
High-quality O-rings are essential for the safe and efficient operation of fuel injectors. Seals such as Viton O-rings are designed to enable the prolonged sealing of injectors under extreme heat conditions.
