Product Details
HELLA’s electronics line draws on long-standing OE competence, and this camshaft position sensor follows that approach with calibrated signal output and durable construction. It is engineered for the Mercedes-Benz C220, C280, C36 AMG, E320, SL320, C230, and SLK230 applications listed below, including 1994-2000 Mercedes-Benz models. If you are replacing a failing camshaft position sensor on a Mercedes-Benz C230 or SLK230, 009121071 provides the correct connector style, seal, and electrical layout for the specified vehicles.
This part cross-references Dorman - HELP 79310 for the same application.
What It Helps Resolve
- Hard starting or extended crank time caused by an inaccurate camshaft signal
- Rough idle or intermittent misfire from timing signal loss
- Check engine light conditions related to camshaft position sensor faults
- Fuel injection timing errors on listed Mercedes-Benz applications
- Ignition timing irregularities tied to sensor signal degradation
Installation Notes and Tips
Assy/disassy by qualified personnel required. Verify the connector shape, 3-pin layout, and seal condition before installation. Confirm the OE reference and vehicle application match the listed fitment for your Mercedes-Benz C230, SLK230, S320, C220, C280, C36 AMG, E320, or SL320. No mounting hardware or wiring harness is included.
Quality Assurance
This HELLA sensor is manufactured to OE fit, form, and function standards and calibrated using advanced diagnostic tools. Corrosion-resistant terminals and protective coatings support long-term durability in demanding engine environments.
