Code P1D74 Dodge Description

This diagnostic compares the gear shift actuator 2nd-4th position to a minimum and maximum threshold values of allowable mechanical positions. The actuator position is read by a position sensor which provides an output signal with Pulse Width Modulation (PWM) at a fixed frequency and duty cycle proportional to the position of the actuator. The PWM duty cycle electrical range is between 10% and 90%. If the position sensor signal is within this electrical range but it indicates the actuator position is outside of its expected mechanical travel, then the diagnostic will be considered failing.

What are the common symptoms of the P1D74 code?

Symptoms may include the transmission not shifting properly, the vehicle stuck in one gear, warning lights on the dashboard, and reduced drivability.

What causes the P1D74 Gear Shift Actuator 'B' Position Out Of Range code?

Possible causes include a faulty gear shift actuator, damaged wiring or connectors in the circuit, sensor failure, or internal transmission issues.

Can I drive with the P1D74 code active?

It is not recommended to drive with this code active, as it could lead to transmission damage or unsafe driving conditions due to improper gear shifting.

How can I diagnose the P1D74 code?

Start by inspecting the wiring and connectors for damage or corrosion, then test the gear shift actuator and associated sensors using a multimeter or diagnostic tool.

What tools do I need to troubleshoot the P1D74 code?

Common tools include an OBDII scanner, a multimeter for testing electrical circuits, and basic hand tools for inspecting and repairing components.

How is the P1D74 code typically fixed?

Repairs may involve replacing the gear shift actuator, repairing damaged wiring, cleaning corroded connectors, or, in rare cases, addressing internal transmission faults.

Can a software update fix the P1D74 code?
