P1476 with two P0326 codes?
I was on the highway yesterday when my check engine light came on once again. This time, it threw different codes. One P1476 (EVAP Emission Control LDP Circuit Malfunction/Insufficient Vacuum) and two P0326 codes (Knock Sensor Circuit Malfunction) i did notice my engine engine is not running very smooth at idle, but seems to drive fine minus some weird hesitation when shifting at times. That has only recently started, so may be due to this EVAP issue? Also had one instance where my car didn’t want to start up easily. But auto store says that I would need to replace the LDP pump. I just want to double check and make sure this is indeed the issue before buying a $130 part. |

The P1476 could be a vacuum circuit tube either being loose or bent/crimped. Have you tested the knock sensor?

Only major issue im having is sometimes the car struggles to start, but once it does, it seems to run fine. Just a minor annoyance. |
Codes defined
P1476 = Leakage diagnostic pump clamped tube
P0326 = Knock sensor Bank 1 |
