How much does an ignition control module replacement cost?
On average, the cost of replacing an ignition control module can vary depending on your vehicle and where you have the replacement done.
How long does it take to replace an ignition control module replacement cost?
The parts cost covers a new Ignition Control Module (ICM) and may also encompass a new set of ignition coils and spark plugs. Regarding labor costs, it typically requires approximately 0.9 hours for a certified mechanic to inspect your vehicle, diagnose the issue, and complete an ignition ignitor replacement.
How did we estimate these prices?
My Mechanic experts researched and collected data from 2500+ real repair shops in all states in Malaysia, 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 MyMechanic in Malaysia, times the number of hours it takes on average to complete a repair.
What parts do I need for my ICM replacement?
Three main categories of ignition systems exist, progressing from oldest to newest: the conventional ignition system, also known as the "contact breaker" or "breaker point" system, followed by the electronic ignition system, and finally, the distributorless ignition system
- The ignition switch completes the circuit, initiating engine startup when the key is turned or ignition switch is activated. Repeating this action interrupts the circuit, shutting down the engine.
- The car battery supplies ignition coils with a low-voltage current once the circuit is closed.
- The ignition control module (ICM) also known as the ignitor, igniter, ignition control unit, or power output stage control, is housed within the distributor. It calculates and signals the precise timing for ignition coil firing, optimizing engine efficiency.
- Ignition coils transform the car battery's 12-14V current into 60-120,000 volts of power.
- Ignition cables, or spark plug wires transmit the voltage from the ignition coils, timed by the distributor caps, to the spark plugs.
- Spark plugs create a high-voltage spark across a gap in each engine cylinder, igniting the air-fuel mixture at the correct moment. These controlled combustions start your car's engine.
Remember, restoring your car may involve installing a new ICM and replacing the ignition switch, ignition coils, and spark plugs.
OEM parts generally come at a higher price compared to aftermarket alternatives, but they often come with superior warranties. For instance, if a certified Toyota mechanic installs a genuine ICM in your car, you'll receive a 24-month/25,000-mile warranty.
You can purchase a replacement aftermarket ICM replacement from MyMechanic or contact them for further assistance.
Where can I get my ignition control module replaced?

How did we vet these shops?
My Mechanic experts researched 2500+ real repair shops across the Malaysia. We talked to real shop customers, and analyzed both real shop pricing data and thousands of real customer reviews from each shop to verify them individually.
How will a mechanic replace an ICM?
Replacing the ICM necessitates basic tools and a degree of familiarity with the ignition and electrical systems. When seeking assistance from a garage, they will:
- Disconnect the car’s battery.
- Remove the engine cover and access the distributor. Take off the distributor cap and rotor.
- Uninstall the old ICM, inspect the connections, and clean them if needed. Install the new ICM.
- Replace all other parts, reconnect the battery cables, and test the vehicle's ignition.
What happens when the ignition control module goes bad?
Ignition coils play a crucial role in both your car’s ignition and powertrain systems. Depending on the severity of the issue, your driving capability may be affected by:
- If the ICM fails to activate the ignition coils and start the engine, your vehicle won't be able to move. It's crucial to address this issue promptly to avoid being stranded.
- Engine misfires: A malfunctioning ICM may fail to activate the ignition coils correctly, leading to misfires. Misfires can result in stalling, rough idling, shaking, and pose a risk of engine damage if left unresolved.
- A faulty catalytic converter: If fuel floods the engine cylinders but fails to ignite, it travels through the exhaust system to the catalytic converter. Raw gasoline can damage the converter over time if a faulty ignition control module is neglected.
What is an ignitor replacement?
An ignitor replacement is a straightforward procedure that involves replacing an electrical component in your car's ignition system responsible for timing the ignition coils.
The ICM is a small plastic component with multiple wiring connections, housing a circuit board with basic programming. It is susceptible to failure due to overheating, short circuits, or exposure to moisture.
When should I replace my ignition ignitor?
Identifying a failing ICM can be challenging without evident damage. Here are some warning signs to monitor:
How long does the ignition control module last?
The ICM is designed to endure the lifespan of your vehicle, yet, akin to most electrical car components, it's vulnerable to power surges, shorts, moisture, and heat. If another ignition component malfunctions, such as the ignition coils or wiring, it may contaminate or damage the ICM. Vibrations and wear can also lead to electrical connection failures.
Can I replace the ignition control module myself?
The ICM is typically straightforward to access and replace, making it suitable for a DIY project. However, caution is essential when dealing with car electronics to prevent shocks from handling wires. It's advisable to consult a detailed repair manual or instructional video before starting the replacement process. Additionally, remember to wear protective glasses as a safety precaution.
FAQs
The ignition control module can fail due to power surges, power shorts, moisture, and heat exposure If another ignition component, such as the ignition coils or wiring, malfunctions, it may contaminate or damage the ICM. Additionally, vibrations and wear can contribute to electrical connection failures.
The ignition control module (ICM) and the ignition coils are distinct components. The ICM is a plastic electronic component situated within the distributor, responsible for regulating the timing of the ignition coils' firing. On the other hand, the ignition coils provide the high-voltage spark required to ignite the fuel in the engine cylinders.
The ignition control module (ICM) is positioned within the distributor, beneath the cap and rotor. Typically, the distributor is situated to the side of inline-four and inline-six engines, while it is on top of V6 and V8 engines. The ICM features a ground wire and both male and female connections.
