If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be a sign of p1901 fault code.

Here are the symptoms to look out for:

  • The P1901 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include issues with the transmission, such as difficulty shifting gears or the transmission slipping.
  • The vehicle may also experience reduced power or acceleration, and there may be a noticeable decrease in fuel efficiency.
  • Additionally, the vehicle may experience stalling or hesitation during acceleration, and there may be a rough idle or misfires.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The P1901 fault code in automobiles can be caused by various factors, including sensor installation, faulty sensors, and electrical connections.

  • The automobile fault code P1901 can be caused by several factors.
  • These include the TSS sensor not being installed correctly, a faulty TSS sensor, an open or shorted TSS sensor harness, and a poor electrical connection in the TSS sensor circuit.
  • It is important to address these issues promptly to prevent further damage to the vehicle.

To fix the p1901 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code P1901, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The factors that influence the cost of fixing the automobile fault code P1901 are the estimated repair time and the hourly rate charged by the auto repair shop. The estimated repair time for this fault code is 1.0 hour. The hourly rate charged by most auto repair shops ranges between $75 and $150 per hour.

These factors are crucial in determining the overall cost of fixing the P1901 fault code.

The P1901 fault code is related to the Turbine Shaft Speed (TSS) sensor in a vehicle. The TSS sensor sends a signal to the Powertrain Control Module (PCM) or Transmission Control Module (TCM) that indicates transaxle turbine shaft input speed.

The P1901 code will set when the TSS sensor signal to the PCM is irregular or interrupted. This fault code is an indication of a problem with the Turbine Shaft Speed Sensor Circuit Intermittent.

What are the possible causes of the P1901 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1901 fault code. This code is caused by a faulty Turbine Shaft Speed (TSS) sensor, an incorrectly installed TSS sensor, a poor electrical connection in the TSS sensor circuit, or an open or shorted TSS sensor harness. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the related wiring harness and connectors to fix the P1901 fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to the P1901 fault code, there are a few possible causes to consider. One of them is a faulty Turbine Shaft Speed (TSS) sensor, which could be caused by an incorrectly installed sensor or a poor electrical connection. To fix this issue, you should visually inspect the related wiring harness and connectors for any damage or corrosion. Check for broken, bent, pushed out, or corroded connector’s pins to ensure a proper electrical connection.
