What are the troubleshooting steps for P281A?

Before starting the troubleshooting process for any malfunction, you should research Technical Service Bulletins (TSBs) for the specific vehicle by year, model, and transmission. In some circumstances, this can save you significant time in the long run by pointing you in the right direction. You should also check vehicle records to verify when the filter and fluid were last changed if possible.

Fluid and Wiring Inspections

The first step is to check the fluid level and examine the condition of the fluid for contamination. Before changing the fluid, you should check vehicle records to verify when the filter and fluid were last changed.

A detailed visual inspection to check the condition of the wiring for obvious defects comes next. Check connectors and connections for security, corrosion, and damaged pins. This should include all wiring and connectors for the transmission pressure control solenoids, transmission pump, and PCM. Depending on the configuration, the transmission pump may be electric or mechanical.

Advanced Steps

Advanced steps always become very vehicle-specific and require appropriate advanced equipment to perform accurately. These procedures require a digital multimeter and vehicle-specific technical references. You should obtain troubleshooting guidelines specific to your vehicle before proceeding with advanced steps. Voltage requirements can be very specific to the particular vehicle model. Fluid pressure requirements will also vary depending on transmission design and configuration.

Continuity Checks

Unless otherwise indicated in the technical data, normal readings for wiring and connections should be 0 ohms of resistance. Continuity checks should always be performed with power disconnected from the circuit to avoid shorting the circuit and creating more damage. Resistance or lack of continuity indicates faulty wiring that is open or shorted and should be repaired or replaced.

What are the common repairs for this code?
