Why You Need This

Getting trigger signals right is non-negotiable in any serious engine build. Whether you're converting a classic Ford Escort to EFI, building a turbo Honda K-series, or setting up a race-spec LS swap, your Haltech ECU needs clean, consistent position reference signals to deliver proper ignition timing and injection events. The Honeywell GT101 technology in this sensor provides exceptional noise immunity and temperature stability — critical when you're running high-output builds where timing accuracy directly impacts power and reliability.

We see too many builds struggle with trigger issues because builders try to reuse worn OEM sensors or fit inappropriate aftermarket units. The 18mm mounting diameter makes this sensor perfect for custom brackets and bespoke installations where you need to mount position sensing exactly where your build demands it. Unlike cheap alternatives that can drift with heat or give inconsistent signals under vibration, this Haltech-spec unit maintains precision across the full temperature range your engine will see, from cold starts to flat-out track sessions.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range including Elite 550, 750, 1000, 1500, 2000, and 2500 models, plus Nexus R3 and R5 systems. Works seamlessly with both single and multi-tooth trigger wheel setups — contact our team to confirm the optimal trigger configuration for your specific engine and application.

Complete Your Build

Most customers fitting this trigger sensor also add our GM 1 Bar MAP Sensor (HT-010100) for reliable manifold pressure sensing and an Air Temp Sensor (HT-010200) for proper density compensation. Both sensors integrate perfectly with your Haltech setup and we stock all three items in the UK for fast despatch. Our technical team can advise on the complete sensor package your build needs, plus we offer in-shop installation and calibration services to get your engine management system running perfectly from day one.
