2006 Ford Escape 3.0L with P0340 and P0106 Codes: Symptoms, Diagnosis, and Crankshaft Sensor Location
My 2006 Ford Escape 3.0L is running roughly with a loss of power. After replacing the camshaft position sensor (P0340 code) and clearing the codes, the vehicle still runs poorly with knocking sounds. New error codes appeared: P0106 (MAP sensor fault), P2197 (O2 sensor stuck lean on Bank 2 Sensor 1), and P1336 (crankshaft/camshaft position sensor issue). I'm concerned whether this indicates a need to replace the crankshaft position sensor as well. If so, where is it located in the engine compartment? The original camshaft sensor replacement did not resolve the problem, and diagnostics show multiple related issues. Could these codes be linked or indicate a deeper mechanical or electrical fault?
Error codes do NOT automatically require part replacements. For P0340, refer to OBD-II code database: https://www.obd-codes.com/p0340. The key term is 'CIRCUIT' — this may indicate a wiring issue or faulty signal rather than a sensor failure. Check for intermittent connections or corrosion in the harness.
