P1933 Volvo Scc OBD Code

OBD/2 P1933 error code description and symptoms.

The Transmission Fluid Pressure Switch allows the engine's control module (PCM) or Transmission Control Module (TCM) to use hydraulic fluid to engage the clutches in the transmission to allow for smoother shifting while driving. If the PCM or TCM detects an issue with the hydraulic clutch or the pressure switch, the PCM or TCM will set code P1933

Regardless of the design though, the purpose of all clutch actuating systems is to improve the driving experience by removing the need for manual clutch operation by the driver. Computer-controlled clutch actuating systems work particularly well in dual clutch systems where one clutch controls gear changes of even-numbered gear ratios, and a second clutch that controls gear changes of odd-numbered ratios.

P1933 Volvo Scc Error Code Repair Process :

If your vehicle failed a P1933 test and the P1933 Check Engine Light is NOT on, chances are you have a problem with the OBDII system, a burned out MIL lamp, or a faulty catalytic converter. The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses knock sensor 1 circuit intermittent (bank 1 or single sensor) a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look knock sensor 1 circuit intermittent (bank 1 or single sensor): Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature.

Common Causes of Volvo Scc P1933 OBD2 Code

A common cause of code P1933 is the failure of Knock Sensor 1 Circuit Intermittent (Bank 1 or Single Sensor), but there are several other possible causes as well, such as ;

Continuous oil flow to the VCT piston chamber
Faulty Air Flow Meter
Faulty Air fuel ratio (A/F) Sensor 1 Bank 1
Lack of fuel
