P1349 — Camshaft Position Sensor B Range / Performance

For Ford vehicles

fuel level sensor circuit – signal too high

powertrain (engine/transmission)

Is it safe to drive?

Drive with caution Drive with caution. The engine may run poorly or enter a failsafe mode; if timing has jumped, continued driving risks severe valve damage on interference engines. Diagnose before any long trip.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm P1349 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the camshaft position and variable valve timing for damage, corrosion, chafing or poor contact.
  4. Subsystem check Check oil level and condition first — VVT systems are hydraulically operated and sensitive to dirty oil.
  5. Subsystem check Compare commanded vs actual cam position in live data while revving the engine.
  6. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P1349 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P1349 (parts and labor, USD, independent shop rates): Replace the camshaft position sensor: $120–$350; Replace the VVT oil control valve: $200–$500; Timing chain/belt repair: $800–$2,500. Overall, fixing P1349 usually costs between $120 and $2,500. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

What does OBD2 code P1349 mean?

Camshaft Position Sensor B Range / Performance (P1349): a powertrain (engine/transmission) fault affecting the camshaft position and variable valve timing. Short, gentle driving to a shop is usually possible. Most often caused by damaged sensor wiring or reluctor ring, worn timing chain/belt or jumped timing, stuck or clogged VVT oil control valve (OCV).

What is the most common cause of P1349?

The most common causes are: damaged sensor wiring or reluctor ring, worn timing chain/belt or jumped timing, stuck or clogged VVT oil control valve (OCV).

How much does it cost to fix P1349?

Replace the camshaft position sensor — $120–$350; Replace the VVT oil control valve — $200–$500; Timing chain/belt repair — $800–$2,500. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What are the symptoms of P1349?

Drivers most often notice: rough idle and poor low-end torque, engine may not start in severe cases, loss of power, increased fuel consumption.

Will P1349 clear itself?

Sometimes P1349 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

When your scan tool displays P1349, the engine control module has identified a fault within the camshaft position sensor circuit, specifically the B sensor and its relationship to variable valve timing operation. This code belongs to the powertrain category and indicates that the sensor's signal has fallen outside the acceptable range or fails to meet performance expectations. The control unit monitors this sensor constantly, comparing actual camshaft position against expected values. When the discrepancy persists across enough drive cycles to confirm a genuine malfunction rather than a temporary glitch, P1349 gets stored and the Check Engine light illuminates.

The affected system plays a critical role in modern engine operation. The camshaft position sensor tells the ECU exactly where each cam is pointing, which becomes essential information when managing variable valve timing. Many engines use VVT to optimize valve overlap, lift, and timing across different RPM ranges and loads. If the control module cannot trust the B sensor's data, it cannot accurately adjust valve timing. That creates a cascade of problems—from rough running to potential engine damage in serious cases. Freeze frame data accompanies the code, capturing RPM, load, temperature, and speed at the moment the fault triggered, giving you the exact conditions to reproduce during testing.

Common Symptoms of P1349

  • Check Engine Light remains illuminated after startup
  • Engine idles roughly with noticeable vibration
  • Noticeable loss of low-end torque and overall power
  • Fuel economy drops noticeably compared to normal driving
  • Extended cranking time before the engine fires
  • In severe cases, the engine may fail to start entirely

What Causes P1349?

The most frequent culprit behind P1349 is a failing camshaft position sensor itself. Electrical components degrade over time, and the sensor's internal circuitry can drift outside specifications. Beyond the sensor itself, several other failures can trigger this code, ordered from most to least probable.

  • Faulty or dying camshaft position sensor
  • Damaged wiring harness or corroded connectors at the sensor
  • Failed VVT oil control valve restricting hydraulic operation
  • Worn or stretched timing chain with jumped timing
  • Contaminated or low engine oil disrupting VVT hydraulics
  • Damaged reluctor ring on the camshaft sprocket

How to Diagnose P1349

Working through this code systematically prevents unnecessary parts replacement and ensures you address the root cause.

  1. Connect an OBD2 scanner and confirm P1349 is present. Record all freeze frame data—this snapshot reveals engine speed, load percentage, coolant temperature, and vehicle speed when the fault occurred. Reproducing those exact conditions during testing dramatically improves your chances of triggering the symptom.

  2. Scan for any other stored codes. P1349 frequently appears alongside other cam, crank, or VVT-related codes that point more directly to the failing component. Address those first if present.

  3. Perform a thorough visual inspection of the camshaft position sensor wiring and connector. Look for chafed wires, broken insulation, moisture intrusion, or bent pins. The sensor lives near the top of the engine where heat and vibration take their toll.

  4. Check engine oil level and condition. VVT systems depend on clean oil flowing through small passages to actuate the timing advance mechanisms. Black, thick, or low oil makes proper VVT operation impossible. Change the oil and filter if contamination is suspected.

  5. Monitor live data while the engine runs. Compare the commanded cam position phaser angle against the actual reading. A large gap between the two values indicates a mechanical or hydraulic issue rather than an electrical sensor failure.

  6. After addressing any discovered issues, clear the code and complete a drive cycle matching the freeze frame conditions. If P1349 does not return, the repair is confirmed. If it recurs, continue investigating the VVT system mechanically.

Repair Options and Costs

Repair costs vary widely depending on which component fails. Always start with the least expensive possibilities before proceeding to major engine work.

  • Camshaft position sensor replacement: $120–$350 (parts and labor)
  • VVT oil control valve replacement: $200–$500 (parts and labor)
  • Timing chain or belt repair including tensioner: $800–$2,500 (parts and labor)

How Much Does It Cost to Fix P1349?

The total bill for P1349 depends entirely on the underlying cause. In most straightforward cases involving only the position sensor itself, expect to pay between $120 and $350. VVT valve replacement typically runs $200 to $500. The expensive scenario—jumped timing or a failed timing chain—can reach $2,500 or beyond when accounting for disassembly and parts. An accurate diagnosis before purchasing components saves money. The priciest repair should never be your first assumption.

Can You Drive with P1349?

Drive with caution. While your vehicle may continue operating, expect poor performance, reduced fuel economy, and potentially a failsafe mode that limits engine speed and power. If jumped timing is suspected on an interference engine, continued driving risks contact between valves and pistons, resulting in catastrophic internal damage. Have this code investigated before any extended road trip.
