I have po325. is this being triggered by the E VAP code?

(1999 Honda Accord)
I have been clearing codes. First it was EGR, E VAP and misfire #2. We cleaned the EGR, I am looking for a canister to do the E VAP and the misfire so far, has stayed clear. The E VAP is back along with the po325. Are these two codes related? When I do the E VAP will the po325 turn off? I am thinking I should do the E VAP first, clear the codes and see what happens...before I go the $100.00+ for a new knock sensor.

P0325 is for the knock sensor circuit.

yes, I know. my question is, once the E VAP is done and I am running properly, should I clear the codes and drive the car to see if the knock sensor code comes back before I go to the expense of replacing the knock sensor? The knock sensor code did not come up the first time the car was scanned. We turned off the misfire #2 and the EGR. E VAP is next, then knock sensor. I was wanting to know if I should turn oof the codes to see if knock sensor comes backafter the E VAP is cleared.

The two codes, evap and knock sensor do not have any commonality. You could clear the code after repairing the evap and see if the knock sensor code reappears. More than likely it will. Drive the car enough to set the OBD monitor for the evap to verify you have repaired that problem. Once you have done that see if you have any pending or permanent codes for the knock sensor.

thank you. So is that 50 miles? I have been told 50 miles (distance) to see if the code triggers, I have also been told that it is "X" miles @ 35mph + "X" miles @ 55mph.... Another question, does the '99 have a window to check the timing belt wear? Timing belt change (water pump, cam, oil plug) will be the next maintence.

No access hole on the 1999. Drive cycle is below.

Step 1 (Engine Cold) Start engine, idle 20 seconds. Accelerate gradually and drive at 20-25 mph for 1 minute, varying speed.

Step 2 Accelerate gradually to 32 mph within 35 seconds. Decelerate to 0 mph in 10 seconds. Idle for 40 seconds.

Step 3 Accelerate at part throttle to 25 mph in 10 seconds. Cruise at 17-25 mph for 15 seconds. Accelerate gradually to 57 mph in 45 seconds. Cruise at 50-56 mph for 1 minute. Decelerate gradually to 0 mph in 40 seconds. Idle for 15 seconds.

Step 4 Accelerate at part throttle to 36 mph and maintain for 10 seconds. Decelerate to 0 mph in 15 seconds. Idle for 5 seconds.

Step 5 Accelerate to 30 mph and back to 0 mph within 30 seconds. Idle for 20 seconds.

Step 6 Accelerate to 36 mph in 20 seconds. Drive at 35 mph for 20 seconds. Decelerate to 0 mph in 15 seconds. Idle 5 seconds.

Step 7 Accelerate gradually to 26 mph and decelerate to 0 within 40 seconds. Idle 15 seconds.

Step 8 Accelerate to 27 mph in 40 seconds. Decelerate to 0 mph in 10 seconds. Idle 25 seconds.

Step 9 Accelerate to 26 mph in 15 seconds, maintain speed for 10 seconds, decelerate to 0 mph in 10 seconds. Idle 15 seconds.

Step 10 Accelerate to 23 mph in 20 seconds, decelerate to 0.5 mph in 10 seconds (no complete stop). Accelerate to 28 mph and back to 0 mph (momentary stop 1 second) within 35 seconds.

Step 11 Accelerate gradually to 34 mph in 45 seconds. Vary speed between 34 and 19 mph for 2 minutes. Decelerate from 25 to 0 mph in 25 seconds. Idle for 5 seconds.

Step 12 Accelerate to 29 mph in 15 seconds, decelerate gradually to 0 mph in 45 seconds. Idle for 30 seconds.

Step 13 Accelerate gradually to 28 mph and back to 0 mph (momentary stop 1 second) within 50 seconds. Accelerate gradually to 27 mph and back to 0 mph within 55 seconds. Idle for 15 seconds.

Step 14 Accelerate to 24 mph and back to 0 mph within 18 seconds. Idle for 10 seconds. Accelerate gradually to 22 mph and back to 0 mph within 50 seconds. Idle for 8 seconds.

Step 15 Accelerate gradually to 30 mph within 50 seconds. Decelerate to 0 mph in 10 seconds. Idle for 25 seconds.

Step 16 Accelerate to 23 mph and back to 0 mph within 30 seconds. Idle for 10 seconds.

Step 17 Repeat steps 1 - 16 once again. Recheck the status of the "Readiness Monitors".

WOW! that is involved! Thank you so much for your help. This is my first Honda. My son has had 2 and when I have driven them, I have really liked them. Now if I can just get the bugs out of the car and feel like I can trust it not to strand me I will be a very happy woman. Although the car is old and high miles (but not for a Honda) I think it is a good car. It is solid as a rock underneath. I drove my '93 Lumina (223,000mi.) to the bone yard and would still be driving it except for the control arm issue...
