DTC P2227-00: BARO Sensor Circuit Range/Performance Problem

P2227: 00 (PCM (H3T)) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	BARO sensor circuit range/performance problem
Detection condition	Any one of the following conditions is met: The condition has continued in which difference in barometric pressure measured and manifold absolute pressure is standard or more, difference in manifold absolute pressure and turbocharger/supercharger boost pressure is standard or more and difference in manifold absolute pressure and exhaust pressure is standard or more. The condition has continued in which difference in barometric pressure measured and manifold absolute pressure is standard or less, difference in manifold absolute pressure and turbocharger/supercharger boost pressure is standard or less and difference in manifold absolute pressure and exhaust pressure is standard or less. Precondition Period vehicle being left: 6 h or more Battery voltage: 8 V or more Within 20 s after engine start The following DTCs are not detected: MAP sensor: P0107: 00 and P0108: 00 Boost pressure sensor: P0237: 00 and P0238: 00 GPF pressure sensor: P0472: 00 and P0473: 00 BARO sensor: P2228: 00 and P2229: 00
Fail-safe	Fixes the barometric pressure for the engine control at 101.32 kPa {1.0332 kgf/cm² , 14.695 psi}.
Possible cause	BARO sensor (built-into PCM) malfunction (Refer to [BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION ] in service information). PCM malfunction (Refer to [PCM REMOVAL/INSTALLATION ] in service information).
Repeatability verification procedure	Clear the DTC recorded in the memory. (See CLEARING DTC .) Start the engine and idle it. Switch the ignition off and wait for 10 s or more.
