Specifications
Numbers the manufacturer's catalogue lists next to this part, grouped by maker. The OE unit's maker comes first. The catalogue does not always state what a number is: it may be the part's own marking or the number of the distributor it fits into.

Which cars it fits
Each row is a separate version as listed by the manufacturer. Years are quoted exactly as the source states them and do not form one continuous compatibility range.
| Car | Body | Engine | Years | Distributor |
|---|---|---|---|---|
| Mazda Xedos 6 144 hp (106 kW). | CA | 2.0 V6 (KF) | 1992/01-1994/05 | T0T52171 |
| Mazda Xedos 6 140 hp (103 kW). | CA | 2.0 V6 (KF) | 1994/06-1999/10 | T0T52171 |
What to take into account
The manufacturer's page lists Nissan for this part — with no model, engine, years or distributor number. Independent sources (a removed original T0T52171 distributor marked J819, a Mazda KF61-18-200 cross-reference catalogue) tie the part to the Mazda Xedos 6 with the KF engine. The same seller's list also names the Xedos 6 1.6 16V (B69N, B6EW), but that matches the model, not the engine: the 1.6 is a four-cylinder, while this part came out of a six-cylinder distributor and the Mazda number starts with KF. We have no confirmation for the 1.6. Check the J819 marking on the removed part and the distributor number before ordering.
If the removed part carries a different number
Besides the OE numbers in the specifications, other numbers turn up next to this part — and they do not mean the same thing. Below is what each of them stands for.
The distributor it fits into
This is the number of the complete assembly, not of the part itself. If you are searching by it, what you need is the component that goes inside that distributor, not the distributor itself. Source: seller listing.

What to check before ordering
- The marking stamped on the removed part: a J, RSB or OE number.
- The number on the complete distributor, if it is legible.
- The connector pin count and the mounting shape.
- The engine, model year and body code of the car.

Description
TIS-2101 — distributor pickup sensor for the Mazda Xedos 6 (CA) 2.0 V6, KF engine family, 1995 cc: 144 hp (106 kW) from 01.1992 to 05.1994 and 140 hp (103 kW) from 06.1994 to 10.1999. It sits inside the Mitsubishi T0T52171 distributor; the Mazda number is KF61-18-200. Replaces Mitsubishi J819. The Xedos 6 1.6 16V versions are not covered: they are four-cylinder, while this part comes out of a six-cylinder distributor.
What it is and where it sits. A round base plate with a central bore for the distributor shaft. It mounts inside the distributor, under the cap and rotor. A sensing element sits on the plate and a slotted disc on the shaft interrupts the gap between the element and its counterpart, so the unit outputs a square-wave signal. In this class of parts the sensing element may be an optocoupler (an LED facing a photo receiver) or a Hall element; a photo of the assembled unit does not establish which, so we do not claim it for this part number. “Hall sensor” is the market name the unit is searched and sold under.
This is not a crankshaft position sensor (CKP) mounted on the engine block near the pulley. The distributor is camshaft-driven and turns at half crankshaft speed. Catalogues list the same part as an ignition module, igniter or distributor Hall sensor.
How it works. The sensor sets the timing but does not create the spark: its pulses go to the ECU and the igniter, which switches the coil primary.
Symptoms that point to this unit. The engine cranks well but never fires — with the signal lost the ECU can cut both spark and injection. Unstable idle, jerking under acceleration and stalling may indicate a broken signal: an oiled slotted disc, a degraded sensing element or a worn shaft bushing. Reddish dust inside the distributor is a reason to inspect the bushing. The coil, the wiring and the fuel system produce the same symptoms, so a symptom alone does not prove this sensor has failed.
Before replacing. The manufacturer does not publish supply voltage, signal levels or pinout for these part numbers, so we quote no figures — take them from the wiring diagram or service manual for your engine. Without a specification, check the rest: a clean and undamaged slotted disc, shaft bushing play, the connector and the wiring. The signal itself is best viewed on a scope — at a steady speed the pulses should be uniform, with no gaps. Rule out the coil and the wiring before replacing anything.
