Whether you’re a hybrid car enthusiast or pursuing hybrid and electrical mechanic training, knowing these potential problems can help keep a hybrid running smoothly. Hybrid cars rely on large, rechargeable batteries to power their electric motor. However, for complex cooling system issues, consult a mechanic.
The CheckEngineLight on your old or new Subaru can indicate various problems, from minor to significant issues. However, knowing the possible causes can help you decide between a DIY fix or consulting certified technicians. Let’s explore the common Subaru CheckEngineLight causes, diagnosis, and associated costs.
While driving, your engine stutters and a flashing CheckEngineLight suddenly appears on your Chevy’s dash. We’re here to explain all aspects of a flashing CheckEngineLight in Chevy cars. The ECU detects this and activates a flashing CheckEngineLight to alert you to the problem.

Common causes for this include: Malfunctioning or dirty throttle body : A faulty throttle body can disrupt airflow to the engine. Dirt or debris can block airflow and interfere with the throttle’s function, triggering the warning light. Is It Safe to Drive with the Throttle Control Light On? Read on to find out.
So, if you notice a TCM issue, immediately consult a professional mechanic at your preferred dealer or auto repair shop. Disconnect the battery to prevent electrical shocks. Check the battery , alternator, and cables often to ensure the TCM has a stable electrical connection. Then, remove the module.
Bottomline: Replacing a blocked DPF is crucial to maintaining engine performance and compliance with exhaust emissions standards. Poor engine performance: When a DPF is clogged, exhaust gases accumulate, causing the engine to lose power and responsiveness.
Each cable terminal clamps onto the positive and negative battery terminal, completing the circuit for proper electricity flow. Other factors that influence the price include: Brand: High-performance battery terminals, known for superior electrical conductivity and corrosion resistance, will cost more. How to Replace Battery Terminals?
Cleaning the throttle body isn’t difficult, but the steps can be confusing, as they differ for mechanical and electrical throttle systems. Then, to avoid electrical accidents, they’ll disconnect the car battery. Step 5: Reinstall the Air Intake Hose and Test The mechanic will reinstall the air intake hose and crank the engine.
Engine oil leaks can also contribute to contamination if the oil reaches the intake system. Electrical Issues: Electrical problems can also result in MAF sensor failure. The CEL serves as a warning to the driver that a fault has been detected in the engine management system.
Meanwhile, in newer, fuel-injected cars, it’s often in a square or rectangular housing between the front grill and the engine. Note : An electric vehicle only has a cabin air filter and not the engine air filter. If you’re confused, consult your owner’s manual for the recommended replacement period.
Newer sensors contain an electric heater that helps them heat up faster and increases the element temperature above exhaust gas temperatures. An electric heater inside the sensor provides added heat to the zirconia element. The heater power comes directly from the vehicle electrical system. In others, it does not.

Spark plug wires are the lifeline that delivers the electric spark from your car’s ignition to the spark plugs, helping your engine start and run smoothly. Engine vibration: Continuous engine vibrations can wear down spark plug wires over time, especially when they aren’t securely fastened or routed.
If you own a car with complex electrical demands, you’ve probably considered getting an advanced lead-acid battery like Absorbed Glass Mat (AGM). But if you’re unsure whether it’s compatible with your car, you can consult a mechanic to verify. But is the battery’s cost holding you back? Any DIY attempt might void the warranty.
A clogged DPF makes the engine work harder to push out the gasses, reducing efficiency. Electrical System Problems Electrical problems prevent the engine from receiving the power it needs to operate efficiently. Cooling System Issues The cooling system is vital for maintaining the engine’s optimal temperature.
This can lead to misfires or even complete engine failure. So, to avoid such costly repairs , consult a mechanic immediately. They’ll also check the wire and electrical connector for poor connections or frayed wiring. Valve test: The mechanic will also use a multimeter to check and compare the solenoid’s resistance.
Engine damage : Insufficient lubrication or oil contamination wears down valve stems, pistons, and cylinders, potentially requiring an expensive engine rebuild. That’s why you should consult a mechanic at the first sign of a valve seal issue. So, it’s best to leave the replacement to an experienced professional.
A remanufactured engine normally costs more than a rebuilt one, as it undergoes a more comprehensive process to ensure optimal quality. Additional repairs: You may also need to address issues with your transmission, cooling system, electrical system, fuel system, engine mount, and drivetrain.
Ignoring it will not only leave you stranded, but it can also put extra strain on your car’s electrical system. Finding the correct battery type : Sourcing a compatible and good battery can take time if it needs to be ordered from a distant location or checked in inventory. Well, your battery might be on its last legs.
If your car’s electrical system is malfunctioning or has a battery warning light on, your alternator might be the sneaky culprit under the hood. Disconnect the negative battery cable: They’ll disconnect the battery’s negative terminal to prevent electrical shocks or shorts during the replacement.
This includes: New alternator bearings: $20 to $80 Labor : $150 to $300 (depending on the alternator type) Note: If the alternator housing and electrical systems are severely damaged, the mechanic will usually suggest replacing the bad alternator. Burning smell from the engine area How Long Do Alternator Bearings Last?
Without coolant flow, the engine’s heat can’t be dissipated. This results in engine overheating and can cause the temperature gauge to spike into the red zone, triggering the CheckEngineLight. This leads to a dead battery and a loss of power for essential functions like lights and ignition.
However, a bad fuel pump (from contaminated fuel and overheating) won’t deliver fuel to the engine. If there’s still fuel in the fuel line, the engine will start briefly and then die. You’ll also notice an illuminated checkenginelight. This reduces engine performance and activates the checkenginelight.
It provides the zap of electricity needed to put all the rest of the electrical components to work. It provides an electric current to the electric-powered starting motor, which then starts the chemically powered internal combustion engine. Either way, it is important to consult with a mechanic.
