In this video I show you how to remove a crankshaft position sensor (CKP) for specific Honda models, then how to replace its o-ring and then finally how to reinstall the CKP sensor. The crankshaft position sensor is typically located either on the timing cover or near the bottom of the engine block, in front of the engine. It's often positioned in proximity to the main pulley, or within the bell housing of the transmission, or near the flywheel.

You may get the below error codes:
Honda P0339 - Crankshaft Position Sensor A Circuit Intermittent Interruption.
Honda P0335: Crankshaft Position Sensor 'A' No Signal.

The crankshaft position sensor plays a critical role in your engine’s operation by monitoring the position and speed of the crankshaft. When it fails, it can cause a variety of drivability issues. Here are the most common symptoms of a faulty CKP sensor :

1. Engine Won't Start
One of the most common signs is the engine cranking but not starting .
The ECU relies on the CKP signal to determine fuel injection and ignition timing. Without it, the engine won’t fire.

2. Intermittent Stalling
The car may suddenly stall while driving , especially under load or when coming to a stop.
Restarting may work after waiting a few minutes — a sign that the sensor might be heat-sensitive or failing intermittently.

3. Check Engine Light Illuminated
A faulty CKP sensor will often trigger the Check Engine Light .
Common diagnostic trouble codes include:
Honda P0344 - Camshaft Position Sensor 'A' Intermittent Interruption
Honda P0335: Crankshaft Position Sensor 'A' No Signal

4. Poor Engine Performance
Misfires, rough idling, hesitation, or lack of power during acceleration.
The ECU uses CKP data to time spark and fuel delivery — if it's inaccurate, performance drops.
5. Backfiring
Incorrect timing due to a bad CKP signal can lead to engine backfiring through the intake or exhaust.
6. Reduced Fuel Efficiency
If the sensor sends incorrect signals, the engine may inject too much or too little fuel, leading to decreased gas mileage .

7. Vibration or Shaking
The engine may vibrate more than usual or feel like it’s running unevenly due to misfires or improper timing.

8. Transmission Issues
In some cases, the transmission may shift poorly or erratically because the ECU is receiving inconsistent engine speed data.

In my particular case I just changed the oring. I had other leaks from the camshaft seal and vtec solenoid gasket, due to age. Thus, I wanted to change this too as it was inexpensive and fairly easy to do.

You will need to do a crank pattern learn procedure if you are replacing a faulty sensor with a scan tool. Without a scan tool do the below:
------------------
1. Start the engine. Hold the engine speed at 3,000 rpm (min −1 ) without load (A/T in P or N, M/T in neutral) until the radiator fan comes on.
2. Test-drive the vehicle on a level road: Decelerate (with the throttle fully closed) from an engine speed of 2,500 rpm (min −1 ) down to 1,000 rpm (min −1 ) with the A/T in 2 position, or the M/T in 1st gear.
3. Repeat Step 2 several times.
4. Turn the ignition switch to LOCK (0).
5. Turn the ignition switch to ON (II), and wait 30 seconds. The CKP pattern learn procedure is complete.
