(1 trip detection logic) Open or short in power steering oil pressure sensor circuit Power steering oil pressure sensor ECM P0552 Power steering oil pressure sensor voltage less than 0.28 V for 0.5 seconds while engine running. (1 trip detection logic) Open or short in power steering oil pressure sensor circuit Power steering oil pressure sensor ECM P0553 Power steering oil pressure sensor voltage more than 4.9 V for 0.5 seconds while engine running. (1 trip detection logic) Open or short in power steering oil pressure sensor circuit Power steering oil pressure sensor ECM MONITOR DESCRIPTION The ECM monitors the sensor voltage and uses this value to regulate the engine idling speed. When the sensor output voltage deviates from the normal operating range, the ECM determines that there is a malfunction in the power steering oil pressure sensor and sets a DTC.
