Bosch crankshaft position sensor 0261210170 — OE direct-fit, high-immunity signal for accurate ignition timing

The BOSCH 0261210170 is an original-equipment crankshaft position sensor that monitors engine rotational speed precisely for correct ignition timing and reliable engine management.

This Bosch sensor matches the component originally installed by manufacturers and is built to withstand harsh under-hood environments. It translates shaft rotation into a digital signal used by the engine control unit to adjust ignition and fuel timing. Because it replicates the factory part’s electrical and mechanical specifications, it’s a direct, cost-effective replacement for compatible Chrysler, Dodge, Jeep, Maybach and Mercedes-Benz models.

How does this sensor maintain accurate ignition timing?

The 0261210170 measures crankshaft rotation with a high-precision digital pickup and sends a clean, noise-resistant signal to the ECU. That information is central to when and how the engine sparks and injects fuel. Bosch designs the sensor to minimize interference and deliver repeatable readings across RPM ranges.

• Digital measurement of rotational speed for consistent signals
• High immunity to electromagnetic interference for stable ECU inputs
• Factory-matched electrical characteristics to preserve timing accuracy

What makes this Bosch sensor durable in hot or cold conditions?

Bosch engineers selected materials and housings that tolerate large temperature swings and the vibrations common near the crankshaft. The internal electronics are sealed and qualified against thermal cycling so performance does not degrade prematurely. That extended life helps avoid frequent replacements and unnecessary diagnostic work.

• Sealed construction resists moisture, oil and road contaminants
• Temperature-rated components for extreme hot and cold operation
• Vibration-resistant build to maintain long-term calibration

Will this part fit my vehicle and replace the original number?

The Bosch 0261210170 is an actual OE replacement compatible with many older Mercedes-Benz, Maybach, Chrysler, Dodge and Jeep applications. Bosch lists common cross-reference numbers and typical fitment ranges, but you should confirm fitment with your vehicle’s year, engine and VIN before purchase. Using the exact OE reference ensures correct electrical and mechanical match.

• Replaces OE numbers such as 0031532728, 05080352AA, A0031532828 and others
• Common fitments include select Mercedes-Benz and Maybach V6/V8 models and certain Chrysler/Dodge/Jeep vehicles
• Always verify fitment using your vehicle’s details or the seller’s fit checker

How does choosing the Bosch OE sensor affect emissions and fuel efficiency?

Accurate crankshaft position data helps the engine computer optimize ignition and injection events, which supports cleaner combustion and better fuel use. While a sensor alone doesn’t guarantee specific fuel economy figures, replacing a faulty or aging sensor with an OE-quality part helps restore intended engine control functionality. Proper timing also reduces misfire risk and engine roughness.

• Restores precise timing signals for stable combustion
• Helps the ECU maintain correct fuel delivery and ignition timing
• Supports reduced misfires and smoother engine operation when installed correctly

Who is this for: Technicians and vehicle owners who need a direct-fit, factory-equivalent crankshaft position sensor for older Mercedes-Benz, Maybach, Chrysler, Dodge or Jeep models. It’s suited to anyone replacing a failed sensor, correcting timing-related drivability issues, or restoring original equipment performance without paying extra for retail packaging.
