P1367 · NissanTDC2 Sensor No Signal

P1367 on Nissan vehicles indicates that the engine control module (ECM) has not received a signal from the TDC2 sensor, which is the second top dead center sensor used to detect the position of the crankshaft or camshaft for cylinder identification and ignition timing. The ECM sets this code when the signal circuit remains inactive or erratic during engine cranking or running, potentially affecting fuel injection and ignition sequencing.

Symptoms you may notice

  • Illumination of the check engine light (malfunction indicator lamp) on the dashboard.
  • Engine may crank but fail to start or may stall immediately after starting.
  • Rough running or misfiring due to incorrect ignition timing and fuel delivery.
  • Loss of power or hesitation during acceleration.
  • Often no symptoms besides the warning light, especially if the engine management system enters a limp-home mode using the remaining sensor.

Common causes, most likely first

  1. Faulty TDC2 sensor (open or shorted internal coil).
  2. Damaged or corroded wiring harness or connector at the sensor or ECM.
  3. Metal debris or contamination on the sensor tip or reluctor wheel, disrupting the magnetic signal.
  4. Improper sensor air gap due to loose mounting or worn timing components.
  5. Failed ECM driver circuit for the TDC2 sensor (rare but possible).
  6. Interference from aftermarket electrical accessories or poor grounds affecting signal integrity.

How to diagnose and fix it

  1. Perform a visual inspection of the TDC2 sensor, connector, and wiring for damage, corrosion, or loose connections.
  2. Check for technical service bulletins (TSBs) or known issues specific to the Nissan model and year.
  3. Measure the sensor resistance and compare to factory specifications; replace if out of range.
  4. Use an oscilloscope to verify the signal waveform at the ECM while cranking; a missing or distorted pattern confirms a sensor or circuit fault.
  5. Check the air gap between the sensor and reluctor wheel; adjust or replace mounting hardware if incorrect.
  6. Inspect the reluctor wheel for cracks, missing teeth, or excessive runout that could cause signal loss.
  7. If all external checks pass, test the ECM signal output and ground circuits; repair or replace the ECM as needed.

TDC2 Sensor Diagnostics Beyond the Basics

  • A failed TDC2 sensor often does not prevent the engine from running because the ECM can substitute the camshaft position sensor signal, so the only clue may be a stored code and slightly degraded performance.
  • Debris accumulation on the sensor tip is a common cause on high-mileage Nissans, and simply cleaning it can restore the signal without replacement.
  • Wiring harness chafing near the timing cover or exhaust manifold can short the TDC2 signal to ground intermittently, setting the code only under certain vibration or temperature conditions.
  • Aftermarket alarm or remote start installations that tap into crank sensor wiring can introduce noise and cause false TDC2 codes.
  • The TDC2 sensor on some Nissan engines is actually a crankshaft position sensor, so misidentifying it as a cam sensor leads to unnecessary parts swapping.

Can I keep driving with P1367?

If the engine starts and runs without noticeable misfire, you can drive cautiously to a repair shop, but avoid heavy acceleration or towing. If the engine stalls, misfires severely, or fails to restart, stop driving and have the vehicle towed to prevent damage or unsafe conditions.
