TDC Sensor No Signal
What it means
This is a Honda- and Acura-specific code; the same number can mean something different on other makes. The engine computer received no signal at all from the top dead center (TDC) sensor inside the distributor. Without it the engine may not start or may stall while driving.
Models covered: Honda and Acura models with distributor-mounted TDC/CKP/CYP sensors, mainly 1990s to early 2000s.
Symptoms4
- Engine cranks but does not start in many cases.
- Engine stalls while driving.
- Check engine light on.
- No spark or no injector pulse when cranking.
Possible causes5
- Failed TDC sensor inside the distributor.
- Unplugged distributor connector or open signal wire.
- Oil leak inside the distributor damaging the sensors.
- Distributor shaft not turning because of a broken timing belt or damaged distributor drive.
- Engine computer fault (rare).
How to diagnose5
- Confirm the distributor shaft turns when the engine is cranked; if not, check the timing belt at once.
- Inspect the distributor connector and wiring for disconnection or breaks.
- Measure sensor signal or resistance against the manufacturer specification.
- Check inside the distributor for oil or damage.
- Check for CYP or CKP codes too; together they point to the distributor or shared wiring.
How to fix5
- Reconnect the connector or repair the open wire.
- Replace the distributor seal and clean it if oil caused the damage.
- Replace the sensor or the whole distributor, depending on part availability.
- Replace the timing belt if broken, and check the engine before starting.
- Set ignition timing, clear the code and confirm normal starting.
Repair cost
In Saudi riyals; the highlighted part is the expected range for this fault.
The cost is low for a connector or wire, higher for a full distributor, and can exceed the range if a broken timing belt caused internal engine damage.
Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.

Frequently asked questions
Why will the engine not start with P1362?
The computer relies on the TDC signal to time spark and injection; without it, it may cut spark or fuel.
Could the timing belt be the cause?
Yes. If the belt breaks, the distributor stops turning and both TDC and CYP signals disappear, so check that the shaft turns first.
