The sensor is at the timing belt side and not in the distributor.
A code 4 can mean P0335 or P0336 therefore an OBD-II code would be more accurate.
Here are the diagnostic procedures.
DTC P0335, P0336, P1361 & P1362: CKP/TDC SENSOR
1. Perform PCM reset procedure. Start engine. If DTC P0335, P0336, P1361 and/or P1362 are indicated, go to next step. If specified DTCs are not indicated, problem is intermittent, system is okay at this time. Check for poor connections or loose wires between CKP/TDC sensor connector and PCM connector. The sensor is at lower part of engine so is prone to contaminations. Repair as necessary.
2. Turn ignition off. Disconnect CKP/TDC sensor 4-pin connector. Measure resistance between CKP/TDC sensor terminals. If resistance between sensor connector terminals is 1850-2450 ohms, go to next step. If resistance is not as specified, replace CKP/TDC sensor.
3. Check for continuity between ground and each CKP/TDC sensor terminal. If continuity does not exist, go to next step. If continuity exists, replace CKP/TDC sensor.
Guess this is all you need for now.
