Detailed Description

This Prenco crankshaft position sensor, part number 4D-1070, is specified for BMW 325i, BMW 325is, BMW 525i, and BMW 525iT applications listed above. The sensor uses a single rectangular connector, blade terminals, and a compact 0.71-inch body diameter to match the original-style electrical and mounting interface on the vehicle. The 26.0-inch harness length supports proper lead routing during replacement service.

As a crankshaft position sensor, this component provides the engine control system with crankshaft position data used for ignition timing and engine management. When the original sensor is worn or failing, drivability and starting concerns can appear. Prenco 4D-1070 is a practical replacement for BMW 325i crankshaft position sensor and BMW 525i crankshaft position sensor service.

What It Is Used For

• Hard starting or extended cranking
• Intermittent stalling or sudden engine shutdown
• Rough running caused by inconsistent crankshaft signal input
• Check engine light concerns related to crankshaft position sensor faults
• Ignition timing or engine speed signal irregularities

Installation Notes and Tips

Verify connector style, terminal count, and harness routing before installation. Inspect the mating connector, wiring, and nearby heat sources for damage before connecting the new sensor. Because no mounting bracket is included, confirm the vehicle’s original bracket or mounting arrangement is in serviceable condition before replacement.

Quality Assurance

Prenco 4D-1070 is built as an OE-style replacement sensor for the listed BMW applications and cross-references Beck/Arnley 180-0411 and Standard Ignition PC231 for the same application.
