Overview

The Hondata 4 Bar MAP Sensor is a direct plug-and-play replacement for the factory MAP sensor on Honda K-series engines. It is required for turbocharged or supercharged setups exceeding stock sensor limits. This sensor can read up to approximately 58 psi (400 kPa), providing accurate manifold pressure data for proper fueling and tuning.
Show original supplier description
The Hondata 4 Bar MAP Sensor is designed as a direct plug-and-play upgrade for Honda K-series engines, specifically when increasing boost pressure. The stock MAP sensor typically maxes out around 11 psi, leading to inaccurate readings and potential ECU guesswork. This 4-bar sensor overcomes that limitation, capable of reading up to approximately 58 psi (400 kPa). Installation is straightforward, as it bolts into the factory location and connects to the OEM connector without requiring any wiring or modifications, making it a quick and reliable solution. Accurate manifold pressure data is crucial for engine tuning, as the ECU relies on this signal for calculating airflow, fueling, and load. By providing reliable readings at all boost levels, this sensor enables safer air/fuel ratios, smoother drivability, and more consistent power delivery. This sensor is commonly used on vehicles with K-series engines and engine swaps, including the 2002–2006 Acura RSX (Base and Type-S), 2002–2005 Honda Civic EP3 (Si), 2001–2005 Honda Civic models with K-series swaps, and the 2005+ Honda S2000. The product comes with one Hondata 4 Bar MAP Sensor.
