P0340 Scion Code - Camshaft Position Sensor Circuit Malfunction
Quick Answer
The Camshaft Position Sensor for the intake camshaft consists of a magnet and MRE (Magneto Resistance Element). Common causes include Faulty Camshaft Position Sensor (For Intake Camshaft), Camshaft Position Sensor harness is open or shorted, Camshaft Position 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.

Code P0340 Scion Description
If no pulse signal is transmitted by the camshaft position sensor despite the camshaft rotating, or the rotation of the camshaft and the crankshaft is not synchronized, the ECM interprets this as a malfunction of the sensor. Also, when the sensor output voltage remains at below 0.3 V, or higher than 4.7 V for more than 4 seconds, the ECM stores a Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P0340 Scion?
- Faulty Camshaft Position Sensor (For Intake Camshaft)
- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)
