The automobile fault code P2784 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of fixing the P2784 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P2784 code is related to the Input Speed Sensor in a vehicle’s transmission system. This sensor detects the primary pulley revolution speed and sends a signal to the Transmission Control Module (TCM) and Engine Control Module (ECM). If the Input Speed Sensor is out of factory specifications, the ECM will set the OBDII code P2784.

This code specifically refers to a correlation issue between InputTurbine Speed Sensor ‘A’ and ‘B’.

What are the possible causes of the automobile fault code P2784?

If you see the engine light on or the service engine soon warning light, it could be due to the P2784 fault code. This code is usually caused by a faulty input speed sensor, an open or shorted input speed sensor harness, or a poor electrical connection in the input speed sensor circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P2784 fault code?

If you’re experiencing the P2784 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Input Speed Sensor or an open or shorted Input Speed Sensor harness. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify any issues and determine the best course of action to take.

What are the signs that the Input Speed Sensor harness is open or shorted, causing the P2784 fault code?
