Electrical & Electronics Services

Modern vehicles are as much computer as they are machine — and at Northstar Automotive Group in Gormley, ON, we have the diagnostic tools and technical expertise to handle both. Master Mechanic Dawood Motala built his career on precision diagnostics, making electrical troubleshooting one of our core strengths. From parasitic battery drains and sensor replacements to advanced driver assistance system calibrations and keyless entry programming, we service the full spectrum of automotive electrical systems for every make and model. Electrical faults are often the most frustrating problems a vehicle can have — intermittent, invisible, and easy to misdiagnose. That's why we take a methodical, diagnostic-first approach that finds the real source of the problem instead of replacing parts until something works. Honest answers, accurate repairs, and electronics expertise you can trust.

Parasitic Battery Drain Diagnosis

We use specialized diagnostic equipment to track down the exact circuit or component draining your battery overnight — because a dead battery every morning isn't a battery problem, it's a detective problem.

Voltage Regulator Replacement

We test and replace failing voltage regulators that cause your alternator to overcharge or undercharge your battery, protecting your electrical system from the damage that comes with unstable voltage.

Spark Plug & Ignition Coil Replacement

We replace worn spark plugs and failing ignition coils that cause misfires, rough idling, poor fuel economy, and check engine lights — restoring smooth, efficient combustion to every cylinder.

Distributor Cap & Rotor Replacement

We inspect and replace worn distributor caps and rotors on older vehicles that cause hard starting, misfires, and rough running — keeping your ignition system firing cleanly and reliably.

Throttle Position Sensor Replacement

We diagnose and replace faulty throttle position sensors that cause hesitation, surging, poor acceleration, and erratic idling — giving your engine's computer the accurate data it needs to run properly.

Mass Airflow Sensor Replacement

We clean or replace mass airflow sensors that cause rough idling, poor fuel economy, and check engine lights by sending inaccurate air measurement data to your engine control module.

Crankshaft/Camshaft Position Sensor Replacement

We diagnose and replace failing crankshaft and camshaft position sensors that cause no-start conditions, misfires, and stalling — critical components your engine's computer relies on to control ignition and fuel timing.

ABS/Traction Control Module Diagnosis

We use advanced scan tools to diagnose ABS and traction control faults, identifying whether the issue is a wheel speed sensor, wiring problem, or module failure before recommending the most accurate and cost-effective repair.

Blind Spot Monitoring Calibration

We calibrate blind spot monitoring systems after repairs, replacements, or collisions to ensure your vehicle's sensors are accurately detecting vehicles in your blind zones — because a miscalibrated safety system is worse than no system at all.

Backup Camera Installation & Repair

We install and repair backup cameras with clean, professional wiring integration so you get a clear, reliable rear view every time you shift into reverse — whether it's a factory replacement or a new aftermarket upgrade.

Dashcam Installation

We professionally hardwire dashcams into your vehicle's electrical system for a clean, wire-free installation that powers on automatically with your ignition and captures everything the road throws at you.

USB/Charging Port Installation

We install additional USB and charging ports integrated cleanly into your vehicle's interior, so you're never running out of power on long drives or fighting over the one port your car came with.

LED Lighting Upgrades

We upgrade your vehicle's interior and exterior lighting to modern LED technology, improving visibility, reducing power consumption, and giving your vehicle a cleaner, more contemporary look.

Trailer Wiring Harness Installation

We install trailer wiring harnesses with proper grounding and weatherproof connections, ensuring your brake lights, turn signals, and running lights communicate reliably between your vehicle and whatever you're towing.

Instrument Cluster Repair

We diagnose and repair faulty instrument clusters with inaccurate gauges, dead displays, or warning lights that won't clear — restoring the dashboard readouts you rely on to monitor your vehicle's vital signs.

Speedometer Calibration

We recalibrate your speedometer after a tire size change, gear ratio modification, or instrument cluster repair to ensure your speed reading is accurate and you're not unknowingly driving over the limit.

Keyless Entry Programming

We program new or replacement keyless entry remotes to your vehicle's receiver so your locks, trunk, and alarm respond reliably — no dealership visit required.

Key Fob Battery Replacement & Reprogramming

We replace key fob batteries and reprogram fobs that have lost their connection to your vehicle, restoring full remote function quickly and affordably without the cost of a full replacement.

Transponder Key Cutting & Programming

We cut and program transponder keys that communicate with your vehicle's immobilizer system, providing a fast, affordable alternative to dealership key replacement when you need a spare or a replacement.

Immobilizer Diagnosis & Repair

We diagnose and repair vehicle immobilizer faults that prevent your engine from starting even with the correct key, using specialized programming tools to restore communication between your key and your vehicle's security system.
