Code P0873 2008 Toyota Camry Description

The Automatic Transmission Fluid (ATF) pressure switch No. 1 is installed in the shift solenoid valve ATF output passage. This switch is used to identify the malfunctioning part when a fail-safe operation is performed. If the shift solenoid valve malfunctions when the ATF pressure switch has a malfunction, a fail-safe operation will be performed. This fail-safe operation is different from the fail-safe operation performed when the solenoid valve malfunctions, and the ATF pressure switch is normal.
The Diagnostic Trouble Code (DTC) will set if the ATF pressure switch No. 1 ON is detected twice when any of the gears from 1st to 4th engages normally.
