P0726 Suzuki Code - Engine Speed Input Circuit Range/Performance
Quick Answer
The Engine Control Module (ECM) monitors the engine speed through the Crankshaft Position (CKP) sensor with the engine running, and send signal to the Transmission Control Module (TCM). Common causes include Faulty Crankshaft Position (CKP) Sensor, Crankshaft Position (CKP) Sensor harness is open or shorted, Crankshaft Position (CKP) Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
