Keep the crankshaft position sensor reading the tone ring exactly as designed with the Walker Products Engine Crankshaft Position Sensor Spacer 235-1378. This paper spacer sets the critical air gap between the sensor and the reluctor/tone ring, and it drops in as a direct OE-replacement across a broad list of 1990–2007 Chrysler and Dodge cars, minivans, and trucks — including the Chrysler 300M, Concorde, Intrepid, and Town & Country and the Dodge Caravan, Grand Caravan, Dakota, and Ram 1500, spanning engines from the V6-2.5L up to the V8-5.9L. See the Buyer's Guide tab for the full list of 82 applications.
The crankshaft signal this spacer protects is what the ECU relies on for ignition timing, fuel delivery, and engine synchronization. If the gap ends up too wide or too narrow, the sensor can produce inaccurate readings that show up as hard starting, misfires, or crankshaft-signal fault codes — signs the spacer may need replacing. Diagnose the cause before replacing, as these symptoms can have other sources.
- Sets the correct sensor gap: maintains proper spacing between the crankshaft sensor and the tone ring/reluctor for consistent signal generation.
- Direct OE-replacement fit: installs between the sensor and the engine block or mounting bracket with no modification or trimming required.
- Matches OE specifications: made to the original thickness and diameter to hold the sensor in its designed alignment.
- Paper spacer: a simple part to replace when it is lost or damaged during sensor service.
Country of origin: United States. Manufacturer part number 235-1378; the listed applications use one spacer each.
