TYIIPLUS™ Automotive Ignition Coil Diagnostic Test Pen

Engine misfiring? Suspect an ignition coil, injector, relay, or motor isn't receiving a pulse?

Stop guessing and start testing. This compact diagnostic pen detects alternating magnetic pulse activity without direct contact, unplugging connectors, or removing parts—making automotive electrical troubleshooting faster and easier.

FEATURES

• Instant Diagnosis without Disassembly: Using advanced technology, this ignition coil tester detects pulse signals without disassembling automotive electrical parts. It quickly and accurately diagnoses ignition systems and other components, providing results in seconds via LED indicators and buzzer alerts—saving valuable diagnostic time.

• Wide Application Range: This ignition coil tester kit can detect various automotive electronic parts, including ignition coils (single-spark/dual-spark/traditional), generators, relays, electric-magnetic valves, fans, fuel injectors, and more. One tool meets multi-system troubleshooting needs across various repair scenarios.

• Simple & Intuitive Operation: Featuring an ergonomic pen-style design and straightforward buttons, this ignition coil tester tool is easy to hold and use. Clear LED status modes and audible buzzer feedback make it simple for both professional mechanics and car enthusiasts to interpret results instantly.

• Quality ABS Build & Battery Powered: Made of high-grade ABS material, this coil pack tester tool withstands frequent use in demanding garage environments. It runs on 2 1.5V AAA batteries (Not Included), so you can start testing right out of the box.

• Automatic Wake-Up Reduces Repeated Manual Operation: When you’re moving around the engine bay, stopping to constantly reset a tool can slow everything down. After 20 seconds without a detected signal, this diagnostic test pen can automatically resume testing when brought near a component with a detectable signal, making quick inspection work smoother.

• Built-In Flashlight Helps In Dark Engine Compartments: Engine bays are rarely bright and easy to see. This diagnostic test pen includes an integrated LED flashlight to illuminate dark areas while you inspect components.

How To Use Your Automotive Diagnostic Test Pen

01. Bring The Tester Near The Component
Place the tip close to the ignition coil, injector, relay, solenoid, motor, or other applicable electromagnetic component housing.

02. Watch & Listen For Feedback
If a magnetic pulse signal is detected, the indicator lights flash and the buzzer sounds. If no pulse is detected, the alerts remain inactive.

03. Continue Troubleshooting Smarter
Use the result as an initial signal check before deciding whether further electrical diagnosis, part inspection, or deeper testing is needed.
