Default Check Engine Light Code p1381
From what I can gather code p1381 (cyp sensor) narrows it down to a bad ecu, distributor or alternator.

I took the cap of the distributor and the rotor was facing down. From what I know it's supposed to face to the upper left correct?
Does that mean I have to replace the distributor or is something else the problem?

Car is a 98 civic ex.

Finally got around to getting a multimeter, didn't have one.

Resistance was .335 on CYP sensor.

Time for a new distributor.

Thanks for the diagram.

From distributor or ECU connector?

From the end of the distributor plug.
