What the T-MAP Sensor 2411082 / 2411528 Does

The T-MAP Sensor 2411082 / 2411528 is a dual-function Temperature & Manifold Absolute Pressure sensor built for the Polaris ProStar EFI engine ecosystem. It merges IAT (Intake Air Temperature) and MAP (Manifold Absolute Pressure) sensing into one high-density module and serves as a direct-fit replacement across the SPORTSMAN, RANGER, RZR, SCRAMBLER, and ACE platforms for 2014–2026 model years.

An integrated NTC thermistor and piezoresistive pressure diaphragm feed your ECU real-time data over a calibrated 0–5V analog output. The ECU uses that data for air-fuel ratio trimming, ignition timing correction, and turbo boost management on forced-induction RZR variants. When this sensor drifts, you get bad fueling, sluggish response, and a queue of codes.

2026 Compliance Snapshot

For 2026, OEM validation requires CAN-bus 3.0 FD (Flexible Data-rate) compatibility in sensor-adjacent ECU pathways. This unit satisfies that standard when paired with updated ECU firmware on 2024+ Polaris models. The short answers:

• 2026 CAN-bus 3.0 compatible? Yes — the analog output integrates seamlessly with CAN 3.0 FD gateways on 2024+ Polaris ECU revisions.
• Fits the 2026 RZR Turbo R? Direct bolt-on — cross-referenced against OEM #2411082 and #2411528 with identical connector pinout and mounting flange geometry.
• Which DTCs does it resolve? P0105–P0108 (MAP circuit), P0110–P0114 (IAT circuit), and P0068/P0069 correlation faults.
• Koeep vs. OEM? Identical form-factor; upgraded high-temp silicone-gel diaphragm rated to 185°C continuous, versus 150°C on the OEM unit.
• 2026 material compliance? Full RoHS 3, REACH SVHC-free, and SAE J1455-compliant vibration and ingress (IP67) certification.

Technical Specifications — Data Backbone

Every value below comes from the sensor's validated specification sheet. Use it to cross-reference before you order.

OEM Platform Cross-Reference: MY2014–2026

One part covers the full Polaris 2014–2026 lineup with form-fit-function equivalence against the OEM service part numbering. Every variant listed uses the identical 3-pin USCAR connector pinout and M6 bolt-down flange pattern, so the swap is like for like. Find your machine on the Koeep product page.

• RANGER — 500, 570 Full-Size, 800 XP, 900 XP, 1000 XP
• RZR — 570, S 800, S 900, XP 1000, Turbo R, Pro R

• ACE — 570, 900 XC

DTC Mapping: What Each Code Means

MAP Circuit — P0105 to P0108

These four codes cover the MAP circuit family under SAE J2012 / ISO 15031-6: P0105 (MAP Circuit Malfunction), P0106 (MAP Range/Performance), P0107 (MAP Low Input), and P0108 (MAP High Input). Missing, out-of-range, stuck-low, and stuck-high signals all trace back to the pressure element or its wiring.

IAT Circuit — P0110 to P0114

On the temperature side, the sensor clears P0110 through P0114, the complete IAT circuit fault range. P0113 (IAT Circuit High) is the code you will see most on cold-soak starts, and the connector is usually guilty before the thermistor is. The FAQ below walks through that call.

Correlation and Turbo Codes — P0068, P0069, P0236–P0238, P0299

P0068 and P0069 fire when the ECU cross-checks the T-MAP pressure reading against throttle position and the two disagree. On forced-induction RZR platforms, the sensor also feeds the rationality checks behind P0236–P0238 (Boost Sensor A Circuit) and P0299 (Turbo Underboost).

Inside the Sensor: 2026 Material Architecture

Glass-Passivated NTC Thermistor

The bead is glass-passivated and suspended in a thermally-conductive epoxy matrix, holding ±1.5% resistance tolerance across the −40°C to +185°C operating envelope. That is a measurable step up from the ±3% tolerance of 2018-era OEM Polaris sensors. The element is built to IEC 60751 Class A with full traceability.

Piezoresistive Pressure Diaphragm

Pressure sensing runs on a bulk-micromachined silicon piezoresistive diaphragm with a proprietary silicone-gel protective coating — the barrier that survives hydrocarbon- and moisture-laden intake air in off-road duty. The Koeep diaphragm is rated 185°C continuous; the OEM sensor's limit is 150°C.

PBT-GF30 Housing and Gold-Plated Terminals

For 2026 the connector housing moved from PA66-GF25 to PBT-GF30 (30% glass-fiber reinforced polybutylene terephthalate). Coefficient of thermal expansion drops 18% for stability under thermal cycling, and the material resists ethanol-blend fuel vapor permeation — a known failure mode in E10/E15-compatible Polaris EFI systems.

Terminal pins are selective gold-plated phosphor bronze (C52100) with 0.8µm minimum plating, holding contact resistance under 5mΩ after 10,000 mating cycles per SAE/USCAR-2 Rev 7.

Service Life and Replacement Intervals

Expect a 3,000–5,000 hour service interval under normal operating conditions. At 200–400 hours per year, that spans roughly the 2026–2030 ownership cycle for the average recreational user.

Heat is the limiter. At a sustained 185°C, the glass passivation layer on the NTC thermistor begins gradual ionic migration after about 4,500 hours. For severe duty — RZR Turbo competition, agricultural RANGER work — replace proactively at 2,500 hours, or any time LTFT values exceed ±12% on a Digital Wrench scan.

Related Electrical Parts Worth Checking

If the T-MAP checks out but the engine still runs rough, test the engine-position sensors next. The PHASE SENSOR for Polaris Hawkeye 300, Ranger 500/570/800, RZR, and Sportsman XP 1000 covers cam-position duty on many of the same platforms this T-MAP serves — worth eliminating before you chase fueling ghosts.

On 2010–2013 RZR 4 800 EFI machines, the Crank Position Sensor #2410720 is the companion part to know, because a dead crank signal means a no-start. For the wider catalog, browse the Starters, Alternators & ECUs collection.
