Are you experiencing problems with your vehicle’s performance? Is your check engine light on?
One possible culprit could be a bad camshaft sensor. But what exactly is a camshaft sensor, and is it safe to continue driving with a faulty one?
In this blog post, we’ll explore the risks and consequences of driving with a bad camshaft sensor.
Is It Safe To Drive With A Bad Camshaft Sensor?
Driving with a bad camshaft sensor is a bit of a mixed bag. Some sources say that it’s safe to drive with a malfunctioning sensor, but it can cause issues with engine performance over time.
You may experience things like misfires, jerking acceleration, and decreased fuel efficiency, which could lead to increased fuel consumption.
However, other sources suggest that driving with a bad camshaft sensor is not safe and could damage your engine.
So while it might be possible to drive with a bad camshaft sensor for a short period, it’s generally not recommended.
If you continue driving with a malfunctioning sensor, it could lead to further issues and potentially cause engine damage.
Common symptoms of a faulty camshaft sensor
Here are some common symptoms to watch out for.
Check Engine Light
One of the first symptoms of a bad camshaft position sensor is a check engine light.
If the engine control module senses something wrong with the sensor, the check engine light will illuminate the dashboard.
A rough idle is a common symptom of a bad camshaft position sensor. The engine may idle roughly, stumble frequently, or even stall frequently.
This problem could be caused by a bad camshaft sensor, EGR valve, or fuel pump.
Reduced Power Output
Sub-optimal combustion of the engine due to a bad camshaft position sensor can result in the engine of your vehicle producing less power.
This may be noticeable when trying to accelerate. On some occasions, your engine can go into “limp mode”.
A faulty camshaft sensor can cause misfires in an engine. The camshaft sensor provides the engine control module with the data needed to synchronize fuel injection and spark timing.
If the data is incorrect or missing, the engine may misfire or hesitate.
Hard Starting or No Starting
A failing camshaft sensor can prevent the engine from starting or cause hard starting.
This is because the engine control module uses the camshaft sensor data to determine when to fire the fuel injectors and the ignition system.
If the sensor is not providing accurate data, the engine may not start or start with difficulty.
How much does it cost to replace a camshaft sensor?
The cost of replacing a camshaft position sensor can vary depending on the make and model of your vehicle, as well as the location and the hourly rate of the mechanic.
On average, one has to pay between $100 and $300, with parts alone costing between $25 and $200.
Labor costs can range from $30 to $130 and may be estimated between $70 and $100 for professional replacement.
To get the best price for the part and associated labor costs, a little market research is recommended.
Can you clean a faulty camshaft sensor?
Here is how to clean a faulty camshaft sensor:
Determine if cleaning is necessary:
Before proceeding with cleaning the camshaft sensor, it’s essential to confirm that it’s the cause of the problem.
Look for symptoms such as misfires, sputtering, or a check engine light. If the sensor has debris on it or appears dirty, cleaning may be necessary.
To clean a faulty camshaft sensor, you will need a few items, including a can of electronic cleaner, a soft-bristled brush, a rag, and a socket wrench.
Disconnect the battery terminal:
Disconnect the black wire from the battery of the vehicle with the help of a socket wrench or any other tool to protect yourself from any kind of shock due to electricity.
Locate the camshaft sensor:
The camshaft sensor is usually located near the engine’s cylinder head, attached to the engine block or timing cover.
Remove the sensor:
Use a socket wrench to remove the sensor from its position. This is usually a simple process that requires the removal of a few bolts.
Clean the sensor:
Once the sensor is out, use a soft-bristled brush to remove any debris, dirt, or grime from the sensor’s surface.
Do not use harsh chemicals or abrasive materials, as they can damage the sensor.
Spray electronic cleaner:
After removing debris from the sensor’s surface, spray electronic cleaner onto the sensor.
Make sure to spray it from different angles, ensuring that all parts of the sensor are covered.
Dry the sensor:
Use a clean rag to wipe the sensor and remove any excess cleaner. Allow the sensor to air dry before reinstalling it.
Reinstall the sensor:
Once the sensor is clean and dry, reattach it to its position using the bolts removed in step 5. Ensure that it’s tightened securely.
Reconnect the battery terminal:
Reconnect the black wire to the battery of the vehicle with the help of a socket wrench or any other tool to ensure that the electrical system is working correctly.
How does a bad camshaft sensor affect engine performance?
A bad camshaft sensor can affect engine performance in various ways. Here are the details:
Engine Performance Problems
A bad camshaft position sensor can cause several engine performance problems such as misfiring, rough running, lack of acceleration, and stalling.
This is because the data from the camshaft position sensor(s) is often used as an input for various engine operations, including fuel injector timing and variable valve timing (VVT) operation.
Decreased Engine Efficiency
When driving with a bad camshaft sensor, engine efficiency will decrease, as it will require more power to run.
This can lead to imbalances in fuel injections and power distribution, which can cause different parts of the vehicle to work harder than they should.
Poor Fuel Economy
A bad camshaft position sensor can cause the alignment of the engine to go off, leading to poor fuel economy.
This is because the sensor helps the engine control unit “know where it is” in the four cycles of the engine.
If the camshaft sensor has failed, the engine may inject fuel and/or spark at the wrong time or with “safe settings,” which can result in poor fuel economy.
The vehicle Refuses to Start
This is because the sensor plays a crucial role in starting the engine by sending a signal to the engine control module to initiate the fuel injection and ignition sequence.
If the sensor is faulty, the engine control module may not receive the necessary signal, preventing the engine from starting.
How to drive with a bad camshaft sensor if you’re in an emergency?
Here are some tips for driving with a bad camshaft sensor in an emergency:
Avoid high-speed driving
You should avoid pushing your vehicle to its limits and instead drive at a moderate speed to reduce the risk of any potential accidents or damage.
Minimize heavy loads
A bad camshaft sensor can cause a decrease in engine power, so it is important to minimize heavy loads to avoid putting extra strain on your vehicle.
This means you should avoid carrying heavy items or towing a trailer, if possible.
Avoid prolonged driving
Driving with a bad camshaft sensor can lead to decreased engine performance and fuel efficiency. It is best to avoid prolonged driving to prevent further damage to your engine.
Get your vehicle checked by a mechanic
You should take your vehicle to a mechanic as soon as possible to diagnose and fix the issue to avoid potential engine damage.
How to prevent camshaft sensor failure?
Here are some tips on how to prevent camshaft sensor failure:
Use high-quality camshaft position sensors that meet or exceed OEM specifications.
Cheap and inferior quality sensors are more likely to fail and can cause additional damage to the engine.
Overheating can cause damage to engine components, including the camshaft position sensor.
Keep an eye on the engine temperature gauge and address any overheating issues promptly.
Check Engine Light:
If the check engine light comes on, it could be a sign of a failing camshaft position sensor.
Have the vehicle diagnosed and repaired promptly to prevent further damage.
Ensure that the camshaft position sensor is installed properly and all connections are tight. Loose or improper installation can cause sensor failure.
