Peterbilt Electronic Replacement Parts

Truck Parts Care lists electronic and electrical replacement parts for Peterbilt heavy-duty trucks, including engine control modules, ABS control units, transmission and body control modules, emission electronics and sensors. These components are used across Peterbilt models such as the 579, 567 and 389, but each part is identified by its own OEM or manufacturer part number.

How to find the right Peterbilt part

The most reliable way to find a replacement is to search the part number printed on the label of your existing component. Peterbilt trucks share many electronic systems with other PACCAR models, but part numbers still differ by build date and specification. If the label is damaged or missing, send us your truck details and VIN and we can help you identify the correct number where possible.

Before you order

Check the condition, core deposit and programming information on each product page. Many electronic modules must be programmed or configured after installation, and some are sold with a refundable core charge.
