C1673 Trouble Code

View C1673 obd/2 error code description and symptoms. C1673 engine photo

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 C1673

Gear changes are accomplished by a command from the TCM to energize the clutch actuator to release the clutch; after which various actuators inside the transmission disengage the current gear, and depending on current operating conditions, engage the next higher or lower gear ratio. All of this happens much faster than a human driver could change gears, and in most applications, gear changes are as smooth and seamless as on any fully automatic transmission.

C1673 Error Code Repair Process :

If your o2 sensor circuit low voltage (bank 1 sensor 1) check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system C1673 and engine control unit are in charge of monitoring a bunch of different o2 sensor circuit low voltage (bank 1 sensor 1), and if they get a reading that's a little out of whack, up pops the check engine light.

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.

Common Causes of C1673

A common cause of code C1673 is the failure of O2 Sensor Circuit Low Voltage (Bank 1 Sensor 1), but there are several other possible causes as well, such as ;

Continuous oil flow to the VCT piston chamber
Failures of clutch motion/travel sensors.
Fuel injector leaks
Faulty Fuel injector
