P1362 · NissanTDC1 Sensor No Signal

Q: What does code P1362 mean?

TDC1 Sensor No Signal. P1362 on Nissan vehicles means the engine control module (ECM) is not receiving a valid signal from the top dead center (TDC) sensor for cylinder 1, which is used to identify the exact position of the crankshaft during the compression stroke. The ECM sets this code when it detects a missing or erratic signal from that sensor while the engine is running or cranking.

Symptoms you may notice

Illumination of the check engine light, often with no other noticeable symptoms
Engine may crank but fail to start, or start after a long crank
Rough idle or misfire, especially when the engine is cold
Reduced engine power or limp mode in some cases
Occasional stalling or hesitation during acceleration

Common causes, most likely first

Faulty TDC sensor (also called crankshaft position sensor) or its connector
Damaged or corroded wiring between the TDC sensor and the ECM
Debris or metal shavings on the sensor tip or reluctor wheel
Worn or damaged reluctor wheel teeth on the crankshaft or camshaft
Poor electrical connection at the ECM harness
Failed ECM (rare, but possible after other causes are ruled out)

How to diagnose and fix it

Scan all modules for stored codes and freeze-frame data to confirm P1362 is the only relevant fault
Inspect the TDC sensor connector and wiring for corrosion, chafing, or loose pins
Check the sensor tip for metal debris and clean it if necessary
Measure the sensor resistance and compare to the manufacturer's specification
Verify the reluctor wheel for missing or damaged teeth using a borescope or visual inspection
Perform a wiggle test on the sensor harness while monitoring live data for the TDC signal
Replace the TDC sensor if resistance or signal output is out of specification, then clear codes and verify

Before you replace the TDC sensor

A loose or corroded ground connection at the engine block can cause a no-signal condition that mimics a failed TDC sensor, so always check grounds first.
Metal debris from a worn starter or flywheel can accumulate on the sensor tip and disrupt the magnetic signal, which is a common oversight.
On some Nissan models, a failing camshaft position sensor can set a TDC-related code because the ECM cross-checks both signals, so don't overlook the cam sensor.
After replacing the sensor, the ECM may need a relearn procedure or a drive cycle to clear the code permanently, so don't assume the fix failed if the light stays on briefly.
Intermittent wiring faults often only appear when the engine is hot or vibrating, so a cold static test may pass while the problem persists on the road.

Can I keep driving with P1362?

If the engine starts and runs without severe misfire or stalling, you can drive cautiously to a repair shop, but avoid heavy acceleration or long trips. If the engine cranks but won't start or stalls frequently, stop driving and have the vehicle towed to prevent safety risks.
