If your Nissan 370Z, Infiniti Q70, or QX56 has logged P0105, P0106, P0107, or P0108, the manifold absolute pressure (MAP) sensor is the first part to check. This guide breaks down the 22365EY00D MAP sensor: what it fits, how its signal works, and how it compares to the OEM revisions it replaces.

The short version: one part number covers three engine families — VQ37VHR (3.7L V6), VK56VD (5.6L V8), and VK50VE (5.0L V8). It outputs a calibrated 0–5V analog signal across a 1-bar absolute pressure range, with a composite housing rated to 150°C continuous.

Essential Specs & 2026 Compliance

Market context matters for parts planning. As of 2026, the global MAP sensor market has surpassed USD 0.9 billion, driven by sustained ICE aftermarket demand and emerging-market vehicle parc expansion (Fact.MR, 2026), with a forecast 14.3% CAGR through 2033 (LinkedIn Market Research, 2026).

Where the 22365EY00D stands on current standards:

• Bus compliance: interfaces with the ECM via ISO 11898 CAN 2.0B physical layer, with full backward compatibility for CAN FD networks rolling out across Nissan/Infiniti 2026 model-year ECUs.
• Parameter mapping: SAE J1939 SPN 106 (Engine Intake Manifold Pressure) and SPN 108 (Barometric Pressure) in heavy-duty diagnostic environments.
• DTC coverage: P0105, P0106, P0107, and P0108 — the complete MAP sensor diagnostic code range.
• Service interval: projected 2026–2030 under normal driving conditions.

The sensor's analog 0–5V signal path is electrically transparent to bus protocol upgrades. The ECM handles CAN FD framing — no sensor-side re-engineering is required.

Technical Deep-Dive: Materials & Signal Architecture

Housing: Glass-Fiber-Reinforced PPS Composite

The sensor uses a piezoresistive silicon MEMS element in a glass-fiber-reinforced PPS (polyphenylene sulfide) body, rated for continuous intake-manifold temperatures up to 150°C and meeting SAE J1639 thermoplastic classification for under-hood powertrain sensor applications.

PPS composites cut component mass by roughly 35% versus die-cast aluminum bodies while resisting fuel vapor, oil mist, and EGR recirculation byproducts — a direct contribution to 2026 CAFE/EPA lightweighting targets. The thermal headroom matters on VK56VD QX56 applications, where engine-bay thermal soak routinely exceeds 120°C.

Connector & Signal Output

The three-pin sealed connector carries the 5V reference, signal return, and sensor ground on gold-plated terminals meeting SAE/USCAR-2 Class 3 vibration and terminal push-force specifications.

The MEMS diaphragm translates manifold pressure into a linear 0.25–4.75 VDC output: 14.7–104.7 kPa on a naturally aspirated VQ37VHR, up to 160 kPa on boosted setups paired with ECM recalibration. Factory calibration points:

• 0.25V ± 0.05V at 14.7 kPa — hard vacuum
• 2.50V ± 0.10V at 59.7 kPa — atmospheric baseline at sea level
• 4.75V ± 0.05V at 104.7 kPa — wide-open throttle, manifold pressure equalized

Specification Matrix: 22365EY00D vs. OEM Benchmarks

The Koeep unit against the two prior OEM generations. The Gen 2 part is still listed as a 22365-EY00B manifold pressure MAP sensor for the Nissan 370Z, Infiniti Q70, M56 and QX56 if you're matching older hardware.

DTC Mapping: P0105–P0108 Under SAE J2012

• P0105 — MAP/BARO Circuit Malfunction.
• P0106 — MAP/BARO Range/Performance: signal out of rationality window during engine-running conditions.
• P0107 — MAP Circuit Low Input: signal voltage <0.25V for >2 seconds.
• P0108 — MAP Circuit High Input: signal voltage >4.9V for >0.5 seconds.

Nissan-specific enhanced codes P0105-00 through P0108-00 are also resolved. For QX56/QX80 fleet work, SAE J1939 SPN 106 (Engine Intake Manifold #1 Pressure) and SPN 108 provide the heavy-duty diagnostic parallel.

P0108 on the QX56: Sensor or Harness?

P0108 on the Infiniti QX56 (VK56VD) means the ECM has read MAP voltage above 4.9V for more than 0.5 seconds where lower voltage was expected — idle or light cruise. In over 70% of 2026 field cases, the cause is a failed sensor with an internal short to the 5V reference rail.

1. Back-probe the signal wire at the sensor connector with a DMM. If it reads 5.0V with key-on, disconnect the sensor. If voltage drops to 0V, the sensor is internally shorted — replace it with the 22365EY00D.
2. If voltage remains at 5.0V with the sensor disconnected, inspect the harness for a short to the 5V reference. Common chafe points: the intake manifold bracket and the firewall pass-through grommet.

Harness shorts, connector damage, and ECM faults live in our Starters, Alternators & ECUs collection — start there when the sensor tests clean but the code keeps coming back.

2026 Electronics: CAN FD & OTA Firmware Updates

Because the sensor is an analog signal device, it is fully transparent to the OTA ECM firmware updates rolling out across the Nissan/Infiniti lineup in 2026. The ECM's ADC samples the 0–5V output at a fixed rate — typically 100 Hz on VQ/VK platforms — so firmware updates adjust lookup tables, not the sensor's physical transfer function.

Installation needs no re-flashing, re-pairing, or initialization. Clear DTCs with an OBD-II scanner and complete a standard drive cycle for the ECM readiness monitor reset.
