Standard Ignition PC87 Engine Crankshaft Position Sensor

Engine Crankshaft Position Sensor for Jeep Applications

Standard Ignition PC87 is an engine crankshaft position sensor built for accurate timing signal delivery in select Jeep applications. It uses a female connector with 3 male blade terminals and is engineered for consistent signal output in demanding ignition systems.

Key Features

• Integrated A/D conversion and digital signal processing for precise sensor output
• Dynamically adaptive switch point to improve timing accuracy
• Protected circuitry to help resist stray electromagnetic fields and power spikes
• Custom magnetic circuit calibration for target wheel and sensor synchronization
• End-of-line testing for timing, pulse width, and signal amplitude
• Female connector, 3 male blade terminals

Detailed Description

Standard Ignition PC87 is an OE-style crankshaft position sensor for Jeep Cherokee, Jeep Comanche, Jeep Wagoneer, and Jeep Wrangler applications listed below. The sensor is calibrated during performance testing to improve timing accuracy between the target wheel and sensor output, while built-in signal processing helps maintain stable operation. This part cross-references Dorman - OE Solutions 907-776 for the same application.

Compatible With 1988-1990 Jeep Cherokee, N/A; 1988-1990 Jeep Comanche, N/A; 1988-1990 Jeep Wagoneer, N/A; 1987-1990 Jeep Wrangler, N/A w/o High Altitude Emissions; 1986-1987 Jeep Cherokee, N/A w/o High Altitude Emissions; 1986-1987 Jeep Comanche, N/A w/o High Altitude Emissions; 1985-1987 Jeep Wagoneer, N/A w/o High Altitude Emissions.

Common Uses

• Restoring crankshaft position signal accuracy on Jeep ignition systems
• Addressing intermittent no-start conditions tied to crank signal loss
• Correcting rough running caused by unstable timing input
• Replacing a sensor with damaged terminals or connector wear
• Resolving engine stalling related to inconsistent sensor output

Installation Notes and Tips

Verify connector style, terminal count, and vehicle emissions configuration before installation. On Jeep Wrangler, Cherokee, Comanche, and Wagoneer applications, confirm whether the vehicle is equipped without High Altitude Emissions where noted. Inspect the target wheel, wiring, and connector terminals for damage before installing the new sensor.

Quality Assurance

Standard Ignition maintains control from component sourcing through finished product manufacturing. PC87 is tested for timing, pulse width, and signal amplitude, with environmental and endurance validation performed to support consistent operation.
