OBDResource 5V/12V Fuel Injector Tester & Adapter Kit – Custom PWM Pulse Signal, Adjustable Pulse Count, LED Display Injector Diagnostic Tool

Product Description

The OBDResource Fuel Injector Tester & Adapter Kit is a professional injector diagnostic tool engineered for modern fuel systems, featuring dual-voltage testing (5V and 12V), custom PWM pulse control, and adjustable test counts. Unlike many injector testers on the market that only support 12V fixed patterns, this advanced tester is designed to work with a wider range of injector types and control strategies, helping technicians perform more accurate injector activation and comparison tests.

With 5V/12V selectable output, the tool supports both low-voltage and standard injectors, reducing the risk of over-driving sensitive components and improving compatibility across more vehicles. The custom PWM pulse signal function allows you to simulate real ECU control signals, fine-tune pulse behavior, and evaluate injector response more realistically. You can also set the exact test count to repeat consistent cycles for comparison testing, cleaning verification, and spray pattern validation.

Featuring a clear LED display, user-friendly controls, and a multi-connector adapter kit, this injector tester is ideal for repair shops, fleet maintenance, injector service businesses, and serious DIY users who need precise, repeatable injector diagnostics.

Key Features

Dual Voltage Testing: 5V + 12V Output
Supports both 5V and 12V injector activation to match different injector designs and vehicle control requirements, offering broader compatibility than standard 12V-only testers.

Custom PWM Pulse Signal Control
Create and adjust PWM pulse behavior to better simulate ECU injector control signals, enabling more realistic testing and improved fault diagnosis.

Adjustable Test Count for Repeatable Results
Set the number of activation cycles for consistent, repeatable tests—ideal for before/after cleaning verification and side-by-side injector comparison.

LED Display for Clear Monitoring
Displays working mode, parameters, and test status for fast setup and accurate diagnostics.

Dual Injector Comparison Testing
Supports testing two injectors for direct performance comparison, helping quickly identify weak, clogged, or inconsistent injectors.

Universal Adapter Kit
Includes multiple injector connectors for secure, reliable fitment across common injector types used in gasoline engines.

Safe, Controlled Output
Stable signal output and controlled voltage selection help reduce the risk of damaging injectors during activation testing.

Typical Use Cases

• Diagnose injector clogging, sticking, leakage, or weak response
• Verify injector performance before installation
• Compare two injectors side-by-side for consistency
• Confirm injector cleaning results with repeatable pulse cycles
• Simulate ECU control using custom PWM signal settings
