It clips onto a coil-on-plug and picks up the ignition waveform so that the tool you already own can display it — and that waveform is the closest thing in engine diagnostics to a window into the combustion chamber.\u003c\/p\u003e \u003cp\u003eSold under Topdon and carrying the Hantek name, it belongs to a small family of tools that answer questions no fault code can. A code tells you a cylinder is misfiring. The ignition waveform tells you \u003cem\u003ewhy\u003c\/em\u003e.\u003c\/p\u003e \u003ch3\u003eWhat the waveform actually shows you\u003c\/h3\u003e \u003cp\u003eThe current product data frames this as a list of questions, and they are worth reading as exactly that — the specific things a technician goes looking for on the trace:\u003c\/p\u003e \u003cul\u003e \u003cli\u003eDoes the ignition plug need replacing, or only cleaning?\u003c\/li\u003e \u003cli\u003eIs the fuel injector in the electronic fuel injection system working properly?\u003c\/li\u003e \u003cli\u003eIs there a problem with the leakproofness of the cylinder?\u003c\/li\u003e \u003cli\u003eHas the gap between the plug electrodes opened up?\u003c\/li\u003e \u003cli\u003eHas the electrode shape gone sharp?\u003c\/li\u003e \u003cli\u003eIs there oil contamination or carbon deposit on the plugs?\u003c\/li\u003e \u003cli\u003eHas the insulating property of the plug deteriorated?\u003c\/li\u003e \u003cli\u003eIs there a problem with the power supply from the storage battery?\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eWhat links that list together is that every item on it is a \u003cem\u003econdition\u003c\/em\u003e rather than an event. A scan tool records events — a misfire counted, a code set. Conditions are what cause events, and they are visible on a waveform long before they are severe enough to set a code. A plug gap that has grown, a cylinder losing its seal, a weak supply voltage: each of them changes the shape of the burn, and each shows up as a change in the trace while the engine is still running acceptably.\u003c\/p\u003e \u003ch3\u003eWhy a probe, rather than pulling plugs\u003c\/h3\u003e \u003cp\u003eThe alternative diagnosis is mechanical: remove the coils, remove the plugs, inspect them, put it all back. On a modern engine that is an hour of labour before anyone has learned anything, and it destroys the evidence — a plug tells you its own history but not what the cylinder is doing at three thousand revolutions per minute under load.\u003c\/p\u003e \u003cp\u003eA probe gathers the same evidence while the engine is running, at the condition the fault actually appears in. That is the difference between diagnosing a cold engine on a bench and diagnosing a hot engine at the moment it misbehaves.\u003c\/p\u003e \u003cp\u003eIt also scales. Once the probe is on, comparing one cylinder against its neighbours is quick, and comparison is how ignition faults are usually found — not by knowing what a perfect trace looks like, but by noticing that one cylinder does not look like the other five.\u003c\/p\u003e \u003ch3\u003eCheck this before you order\u003c\/h3\u003e \u003cp\u003eHere is the honest limit of the published information.

Nothing further is itemised in the listing data, so this page does not claim adapters, leads or a case. There is no oscilloscope or scan tool included — this is an accessory for equipment you already own.\u003c\/p\u003e \u003ch3\u003eCertification and compliance\u003c\/h3\u003e \u003cp\u003eNo third-party safety or conformity listing is published for this item in the data we hold, and nothing here should be read as claiming one. For a passive capture accessory that is the ordinary situation: approvals of that kind attach to the measuring instrument, not to the probe feeding it. If a fleet, dealer or workplace policy requires named documentation for diagnostic equipment, that requirement sits with the scope or scan tool — ask us and we will help you obtain the current manufacturer paperwork for it.\u003c\/p\u003e \u003ch3\u003eA safety note worth reading\u003c\/h3\u003e \u003cp\u003eSecondary ignition is a high-energy environment and the engine is running while you work. Follow the instrument manufacturer's instructions for connecting a probe of this kind, keep leads clear of belts, fans and hot surfaces, and do not improvise a connection to an instrument the probe was not intended for.\u003c\/p\u003e \u003ch3\u003eShipping and delivery\u003c\/h3\u003e \u003cp\u003eA small parcel item, shipping to addresses in the lower 48 states, or available for collection from the warehouse. The cost is calculated for your address at checkout rather than quoted here, because carrier pricing moves. Inspect the probe and its connector as soon as it arrives and note any damage on the delivery paperwork at the time — a crushed connector is obvious on the day and hard to argue about a fortnight later.\u003c\/p\u003e \u003ch3\u003eWarranty\u003c\/h3\u003e \u003cp\u003eTerms and the claim process are on our \u003ca href=\"https:\/\/mechanicsuperstore.com\/pages\/warranty-claims\"\u003ewarranty claims page\u003c\/a\u003e. If the probe is faulty, keep it as it arrived and contact us before cutting, re-terminating or adapting the lead. Once a probe has been modified, nobody can tell whether the fault arrived with it or was introduced afterwards, and that is precisely the question a claim turns on.\u003c\/p\u003e \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv class=\"divider\"\u003e\u003cimg src=\"https:\/\/cdn11.bigcommerce.com\/s-ew8kwapfc4\/images\/stencil\/original\/image-manager\/golden-bar.png?t=1681903157\" alt=\"\" width=\"1198\" height=\"8\"\u003e\u003c\/div\u003e \u003cdiv id=\"kd-main-product-downloads-container\" class=\"kd-main-product-downloads-container\"\u003e \u003cdiv class=\"panel\"\u003e \u003cdiv class=\"kd-product-downloads-continer kd-flex-row\"\u003e \u003cdiv class=\"kd-prouduct-downloads-item\"\u003e \u003cdiv class=\"kd-img-container kd-flex-row\"\u003e\u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv class=\"divider\"\u003e\u003cbr\u003e\u003c\/div\u003e","brand":"TOPDON","offers":[{"title":"Default Title","offer_id":49287144931482,"sku":"COPSP","price":73.49,"currency_code":"PKR","in_stock":true}],"url":"https:\/\/coretarps.co.uk\/products\/topdon-usa-hantek-coil-on-plug-signal-probe-diagnostic-accessory","provider":"My Store","version":"1.0","type":"link"}
