on my 01 Civic, when it is cold it starts fine, after 3-5 minutes it starts to run rough and engine dies.
Starts right up but runs rough. When you give it gas it coughs thru the carb, as if not getting any fuel.
The handheld computer shows code P1362- TDC SENSOR. Honda techs have never heard of this TDC sensor.

Any ideas?

Thanks.

 

TDC is short for Top Dead Center. The sensors that tell the computer where TDC is are the Crankshaft Position Sensor or Crank Angle sensor or the Camshaft Position Sensor. To test this, your going to want to hook up both sensors to a lab scope and check the waveforms. The tech should know what to do. The wave should look like the graph of sin(x), i think (for both sensors).

What engine, trim, and model (coupe, sedan) do you have?
Edit: I just looked up the code P1362. The code is saying that the TDC sensor is not sending a signal to the PCM. The TDC sensor tells the PCM (computer) the position of No.1 cylinder for the sequential fuel injection. The TDC sensor is also knows as the Camshaft Position Sensor, it is NOT the crankshaft position sensor that i said it could be.

More Edit: To determine if the problem is sensor related or wiring related, there is a test you can do. Hook the scan tool up and look at the datastream values for the TDC sensor. Now disconnect the TDC sensor, the readings on the scan tool should should 0V. Next, short the connector (paperclip between terminal 1 (brn/yel) and terminal 3 (yel/blk)) . The reading on the scan tool should goto 5V. Now if the readings change when you disconnect the sensor and short the connector, then the wiring is not your problem. The problem could be that the sensor is bad. Be careful shorting the sensor, im pretty sure nothing will happen since ive done it to other sensors but for some reason i have the idea that shorting things is a bad idea.
