Honda K20Z3 Map Sensor 37830-PNC-003

If your K20Z3 is throwing a MAP sensor code — P0106, P0107, or P0108 — or you're chasing a rough idle, poor fuel economy, or a hesitation under load, this is the part you need. This is the genuine Honda OEM Manifold Absolute Pressure (MAP) sensor, part number 37830-PNC-003, built to the exact specification your K20Z3 engine management system expects.

Your MAP sensor is one of the most critical inputs your ECU relies on. It reads intake manifold pressure in real time and feeds that data to the ECU so it can calculate air density and mass airflow — then adjust fuel trim and ignition timing accordingly. When this sensor drifts or fails, your ECU is essentially flying blind. Fuel mapping goes off, idle quality suffers, and in a modified K-series build, the problem compounds fast. An aftermarket replacement might fit the port, but if its voltage output curve doesn't match the OEM calibration your ECU expects (0.5V at low load, scaling to 4.5V at high MAP), you'll chase sensor-related gremlins that a scan tool won't fully resolve. The OEM unit eliminates that variable entirely.

This sensor is used across a wide range of Honda and Acura applications — not just the Civic Si. The 37830-PNC-003 is the OEM-spec part for the 2006-2011 Honda Civic Si (K20Z3), and it also fits the 2004-2007 Accord, 2005-2008 Element, 2005-2008 Pilot, 2005-2008 TL, 2006-2008 TSX, 2005-2006 RSX, and more. Check the fitment tab for the full vehicle list before ordering — this part number crosses into several K-series and J-series platforms.

At Hybrid Racing, we stock this part because K-series builds are our focus. Whether you're returning a stock Civic Si to factory spec or refreshing sensors on a built K20, getting the OEM part from a shop that knows the platform means you're not guessing on fitment or quality. Each unit ships new in OEM packaging with the O-ring included — ready to install.
