Ford Ranger Engine Crankshaft Position Sensor Kits
Ford Ranger Engine crankshaft position sensor kits
Starting at $30.95, AutoBuffy stocks 2 engine crankshaft position sensor kits from Standard Ignition for the Ford Ranger. The crankshaft position sensor monitors crankshaft speed and position, feeding real-time data to the ECU to control ignition timing and fuel injection. When it fails, the engine may stall, misfire, or refuse to start entirely.
Signs your Ford Ranger needs a new crankshaft position sensor
- Check Engine light on with codes P0335, P0336, P0337, P0338, or P0339 stored in the ECU
- Engine cranks normally but will not start, because the ECU has no position signal to trigger spark or injection
- Intermittent stalling at idle or low speed, often worsening as the sensor heats up during normal driving
- Rough, erratic idle with noticeable RPM fluctuation on the gauge even when the vehicle is stationary
- Hesitation, stumbling, or misfires during acceleration as timing data drops out momentarily
- Engine runs normally when cold but stalls repeatedly once fully warmed up, a classic heat-related sensor failure pattern
Which crankshaft position sensor kit should you buy for your Ford Ranger?
Kits vary mainly by sensor construction (inductive vs. Hall-effect), whether the connector pigtail and hardware are included, and OE-match quality. Confirm which sensor type your Ford Ranger uses — Hall-effect sensors require voltage supply and ground wires, while inductive (magnetic) sensors use only two signal wires. Choosing a kit that matches your factory design avoids adapter wiring and calibration issues.
OE-Equivalent Kit
Best for
Drivers who want a direct factory replacement with no modifications
What you get
Sensor matched to OEM connector type and reluctor ring tooth count, plus mounting hardware and a pre-terminated pigtail
Premium / OEM-Brand Kit
Best for
High-mileage vehicles or owners who want maximum reliability and longevity
What you get
Higher-grade internal coil or Hall-effect chip, heat-resistant housing, extended connector pigtail, and all seals included
Economy Replacement Sensor
Best for
Budget-conscious repairs on vehicles with lower miles remaining or short-term use
What you get
Bare sensor only; compatible connector type, but pigtail and mounting bolt may need to be reused from the original
Two-Sensor Kit (Bank 1 & Bank 2)
Best for
V-configuration engines or vehicles with both a crankshaft and camshaft sensor showing codes simultaneously
What you get
Both sensors in one package ensuring matched signal characteristics, reducing the need for a second repair visit

Replacing the engine crankshaft position sensor on a Ford Ranger

Locate the crankshaft position sensor on the engine block near the crankshaft pulley or flywheel, disconnect the negative battery terminal, then unplug the wiring harness connector and remove the retaining bolt to extract the old sensor. Clean the mounting bore, install the new sensor from the kit, snug the bolt to the manufacturer's recommended feel without over-tightening, and reconnect the harness. Reconnect the battery, clear any stored fault codes with a scan tool, and run the engine to confirm stable idle and no returning codes before returning the vehicle to service.
Frequently asked questions
How much does it cost to replace crankshaft position sensor kits on a Ford Ranger?
Parts start at $30.95 for the Ford Ranger at AutoBuffy. Add shop labor of roughly one to two hours at local rates if you are not doing the job yourself. Total out-of-pocket cost varies by location and how accessible the sensor is on your specific engine, but DIY installation keeps costs close to the part price alone.
Can I drive my Ford Ranger with a failing crankshaft position sensor?
You should not drive the Ford Ranger with a known bad crankshaft position sensor. The engine may stall without warning in traffic, and because the ECU relies on this signal for timing, continued operation can cause misfires severe enough to damage the catalytic converter. A no-start condition can occur at any time once the sensor fails completely.
Will replacing the crankshaft position sensor clear the Check Engine light on my Ford Ranger?
Yes, if the stored code is directly caused by the sensor fault. After installation, use an OBD-II scanner to clear the code manually, or the ECU will clear it automatically after several successful drive cycles without the fault recurring. If the light returns, inspect the reluctor ring and wiring harness for damage before replacing the sensor again.
Does the crankshaft position sensor need to be programmed or relearned after replacement on the Ford Ranger?
Some engines require a crankshaft position sensor relearn procedure after replacement to allow the ECU to reestablish accurate timing calibration. This is typically done with a scan tool or by following a specific idle relearn drive cycle. Check your service manual for the Ford Ranger to confirm whether a relearn is required before returning the vehicle to normal use.
What is the difference between a crankshaft position sensor and a camshaft position sensor on the Ford Ranger?
The crankshaft position sensor tracks the rotation speed and position of the crankshaft at the bottom of the engine and is the primary timing reference for spark and injection. The camshaft position sensor monitors the camshaft at the top of the engine for valve timing on fuel-injected engines. Both affect engine performance, but crankshaft sensor failure is more likely to cause a no-start condition.
How long does a crankshaft position sensor last on a Ford Ranger?
Crankshaft position sensors are not a scheduled maintenance item, but most last somewhere in the range of 75,000 to 150,000 miles under normal conditions. Heat cycling, oil contamination from nearby gasket leaks, and vibration are the main causes of early failure. Replacing a leaking crankshaft seal at the same time can extend the new sensor's service life.
