B0749 Lancia Lambda OBD Code

OBD/2 B0749 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 B0749

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code B0749, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code B0749 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

B0749 Lancia Lambda Error Code Repair Process :

If your vehicle failed a B0749 test and the B0749 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 vehicle speed sensor out of self test range 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 vehicle speed sensor out of self test range: 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 Lancia Lambda B0749 OBD2 Code

A common cause of code B0749 is the failure of Vehicle Speed Sensor Out Of Self Test Range, but there are several other possible causes as well, such as ;

Continuous oil flow to the VCT piston chamber
Faulty select solenoid
Faulty TCM or TCM programming
Camshaft advance mechanism binding (VCT unit)
