diesel Chyba P0238 vysoký vstup obvodu snímače MAP č. 1

[DonFabi]

Zdravím vás potreboval by som pomôcť bol som na emisnej včera s mazdou 6 2.2 skyactiv 110kw a po prvom meraní ako sa pridalo na max. vyhodilo chybu P0238. Snímač tlaku v sacom potrubi sa vyčistil aj sa vyskúšal vymeniť ale bez úspešne chyba sa nedá ani vymazať hneď je späť.

DTC P0238:00​	MAP sensor No.1 circuit high input​
DETECTION CONDITION​	• The PCM monitors the input voltage from the MAP sensor No.1. If the input voltage at the PCM terminal 1BK is above 4.8 V for 5 s, the PCM determines that the MAP sensor No.1 circuit has a malfunction. MONITORING CONDITIONS ― Battery voltage: 8—20 V ― 0.5 s have elapsed after the ignition was switched ON (engine off or on) Diagnostic support note • This is a continuous monitor (CCM). • The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA/Snapshot data is available. • DTC is stored in the PCM memory.​
FAIL-SAFE FUNCTION​	• Stops compressor bypass solenoid valve • Stops regulating solenoid valve • Stops wastegate solenoid valve​
POSSIBLE CAUSE​	• Turbocharger malfunction • MAP sensor No.1 connector or terminals malfunction • PCM connector or terminals malfunction • Short to power supply in wiring harness between MAP sensor No.1 terminal C and PCM terminal 1BK • MAP sensor No.1 power supply circuit and signal circuit are shorted to each other • Open circuit in wiring harness between the following terminals: ― MAP sensor No.1 terminal C—PCM terminal 1BK ― MAP sensor No.1 terminal B—PCM terminal 1BI • MAP sensor No.1 malfunction • PCM malfunction​
