This is a manufacturer-specific code. Its exact meaning can differ between makes; the definition below follows the most common usage.

What it means

P1349 is stored when the Camshaft Position Sensor B Range signal is electrically valid but does not make sense compared with other sensors or the expected operating range. The circuit is usually fine; the component or what it measures is out of specification.

This entry is compiled automatically from the standard definition and typical diagnostic practice for this type of fault. A detailed, reviewed article is in preparation.

Symptoms

  • Check engine light on
  • Rough or unstable idle
  • Hesitation or poor acceleration
  • Increased fuel consumption
  • Possible limp mode with reduced power

Common causes

  1. Camshaft Position Sensor B Range worn, contaminated or out of calibration
  2. Mechanical problem in the system the sensor measures
  3. Air, vacuum or exhaust leak influencing the reading
  4. Wrong or low-quality replacement part
  5. Wiring resistance causing a small voltage offset

How to diagnose

  1. Compare the live Camshaft Position Sensor B Range reading with a known-good value or a second sensor at idle and at 2500 rpm
  2. Check for air, vacuum or exhaust leaks that could skew the reading
  3. Inspect the component for contamination and clean it if the design allows
  4. Verify the part number is correct for the engine
  5. Replace the Camshaft Position Sensor B Range if the reading remains out of specification

Frequently asked questions

Can I keep driving with P1349?

Usually yes for a short time, but expect reduced performance or higher fuel use. Have it diagnosed within a few days.

Will clearing P1349 fix it?

No. Clearing only erases the stored code; it returns as soon as the monitor runs again unless the cause is repaired.
