What the Koeep CMP-2026 Covers for 2026

The Koeep Engine Position Camshaft Sensor is built for the 2026 Stellantis North America platform ecosystem: Chrysler 200 and 300, Dodge Challenger, Jeep Grand Cherokee and Wrangler, and Ram 1500 and 2500. It is a magnetoresistive (MRE) unit calibrated for the Stellantis Global Medium Engine (GME) and HEMI V8 ECU architectures.

• Housing takes continuous 175°C exposure, aimed at the under-hood heat of turbocharged Pentastar 3.6L GME-T6 and HEMI 6.4L Apache variants entering the 2026 model year.
• Response latency is ≤12 µs, with output signal stability from -40°C to +150°C.
• The SENT 3.0 output integrates natively with Stellantis CAN-FD 3.0 backbone networks on 2026+ platforms.
• Compliance covers SAE J2716 SENT 3.0 single-edge nibble transmission, ISO 26262 ASIL-B functional safety, and the 2026 CARB Phase III OBD-3 real-time diagnostic framework.

Materials and Signal Architecture

SmCo Magnetoresistive Element

The 2026 sensor uses a rare-earth samarium-cobalt (SmCo) magnetoresistive element in place of the ferrite Hall-effect designs that drift thermally beyond 140°C. The MRE bridge delivers a ratiometric 0.5V to 4.5V analog output with ≤1% non-linearity across the full thermal envelope, feeding the variable valve timing (VVT) phaser loops on Chrysler's MultiAir III and Dodge's Performance VVT architectures.

PEEK/CF30 Composite Housing

The housing moves from glass-filled PPS to a 2026-spec PEEK/CF30 composite, 30% carbon-fiber-reinforced polyetheretherketone. Tensile modulus at 175°C improves by 40%, and the micro-crack propagation PPS shows after 80,000+ thermal cycles disappears.

That matters most on the 2026 Jeep Wrangler 4xe PHEV and Ram 1500 REV platforms, where hybrid start-stop duty cycles impose 3.7× the thermal-cycling frequency of conventional ICE-only applications.

DTC Mapping for 2026 Diagnostics

Coverage spans the ranges below, validated against Stellantis NGC (Next Generation Controller) and GPEC5 (Global Powertrain Engine Controller 5) ECUs on 2020-2026 model years:

• P0340-P0349 (Bank 1 intake/exhaust): plausibility faults set when the ECU sees missing edges, amplitude dropout, or phase misalignment against the crank reference. The dual-channel redundant output mitigates the single-point failures that commonly set these codes on high-mileage Pentastar 3.6L engines.
• P0365-P0369 (Bank 2): the mirror set for HEMI V8 and 3.0L EcoDiesel applications. Asymmetric target-wheel encoding holds phaser-index recognition at low RPM and high load, where signal-to-noise drops.
• P0016/P0017 (crankshaft-camshaft correlation): often misread as timing-chain stretch on 2015-2025 3.6L Pentastar engines. They usually trace to sensor rise-time exceeding the ECU's 25 µs window; the ≤12 µs latency restores correlation without invasive mechanical repair.
• P0018/P0019: crankshaft-camshaft correlation, Bank 2 extended range.
• P034A/P034B: new for 2026 on HEMI Apache variants; set when MRE bridge output sags below 0.35V peak-to-peak during cranking, a fault legacy Hall-effect sensors cannot self-diagnose.

Installation Protocol

Torque and Sealing

On a 2026 Jeep Grand Cherokee (WL) with the 3.6L Pentastar GME-T6, torque the mounting bolt to 9.5 N·m ± 0.5 N·m (84 ± 4.5 in-lbs). Above 11 N·m you risk micro-fractures in the PEEK/CF30 mounting flange; below 8 N·m, vibration can degrade the signal above 4,500 RPM.

Coat the O-ring with a thin film of dielectric grease (NLGI Grade 2) before installation, and keep the cylinder head mating surface free of debris.

Warning: do not use RTV or anaerobic sealant on the sensor O-ring. It alters insertion depth relative to the target wheel and introduces offset error.

Check the ECU Calibration First

Verify the ECU software calibration index before replacement on any 2026 Stellantis vehicle. Early-production 2026 models may need a PCM flash update, TSB 18-034-26 or later, to enable full SENT 3.0 diagnostic functionality. Without the flash, persistent P0340 shadow codes can remain even with a fully functional sensor installed.

Standards and OEM Cross-References

The PEEK/CF30 housing meets SAE J1637 vibration-fatigue and ISO 16750-4 thermal-shock protocols (1,000 cycles, -40°C to +175°C, ≤10 sec transition). The SmCo element passes IEC 60749-26 semiconductor reliability testing. Production runs under IATF 16949:2016 certified quality systems with full PPAP Level 3 documentation, and OBD-3 readiness is validated per SAE J1979-3 diagnostic service definitions.

Direct cross-reference part numbers:

• Mopar: 5149180AA, 5149198AB, 68080888AA, 68080888AB, 68146091AA
• Standard Motor Products: PC775, PC775T
• NTK/NGK: CM0118
• Bosch: 0261210229
• Delphi: SS12003
• Walker Products: 235-1650

The CMP-2026 carries a 2026-2030 SKU lifecycle profile tied to the Stellantis mid-cycle refresh cadence on the Chrysler 300 (LD), Dodge Challenger (LA), Jeep Grand Cherokee (WL), and Ram 1500 (DT) platforms. Its 100,000-120,000-mile service interval outlasts the OEM unit by roughly 20,000-40,000 miles.
