TDC Sensor Intermittent Interruption
What it means
This is a Honda- and Acura-specific code; the same number can mean something different on other makes. On these models the top dead center (TDC) sensor sits inside the distributor, and the computer uses it for ignition and injection timing. The code means its signal drops out now and then, which can cause stumbling or sudden stalling.
Models covered: Honda and Acura models with distributor-mounted TDC/CKP/CYP sensors, mainly 1990s to early 2000s.
Symptoms4
- Check engine light on.
- Stumbling or bucking while driving that comes and goes.
- Sudden stalling that sometimes restarts after a short wait.
- Hard hot starting in some cases.
Possible causes5
- Loose or corroded distributor connector or wiring.
- Oil leaking into the distributor past its seal and affecting the sensors.
- TDC sensor inside the distributor failing when hot.
- Harness damage from rubbing or heat.
- Worn distributor shaft or bearing giving an uneven signal.
How to diagnose5
- Inspect the distributor connector and wiggle the wiring with the engine running to catch a dropout.
- Check the distributor base and inside for oil.
- Check sensor resistance or signal cold and hot against the manufacturer specification.
- Watch scan data when the stumble happens, if possible.
- Check the distributor shaft for side play.
How to fix5
- Clean and reseat the connector or repair the damaged wire.
- Replace the distributor seal if it leaks oil and clean the inside.
- Replace the sensor if sold separately; otherwise replace the distributor assembly.
- Set ignition timing to the manufacturer specification after fitting a distributor.
- Clear the code and road-test until the engine reaches full temperature.
Repair cost
In Saudi riyals; the highlighted part is the expected range for this fault.
The cost stays low for a connector or seal repair, and rises when the whole distributor must be replaced because the sensors are not sold separately on many models.
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 does P1361 appear only when hot?
A weak sensor or loose connector may work cold and then drop out as parts expand with heat.
Must the whole distributor be replaced?
Not always. Check the connector and oil leaks first; if the sensor is proven bad, the distributor is often replaced because the sensor is not sold alone on many models.
