This is my first post...
Last month I got a CEL on my 2002 Boxster S. I ran an OBD-II diagnostic scan and got two fault codes:
- P0453, fuel tank pressure sensor
- P0327, knock sensor 1
Since my battery was almost five years old and needed to be replaced, I removed the battery and tray to access the fuel tank pressure sensor and discovered two of the three wires to it had become frayed and broken (probably due to vibration and chafing from the sharp metal edge above them, which I cut my finger on). The third wire was also frayed, but not yet broken. I spliced new wire on all three damaged wires, wrapped them, replaced the fuel tank pressure sensor for good measure, put electric tape over the sharp edge above the wrapped wires, reinstalled the battery tray, and installed a new battery.
I started up the car and the CEL did NOT come back on. I have driven the car several times for 162 miles since the repair, and the CEL has NOT come on however, when I run an OBD-II scan the P-0327 fault still comes up. I have cleared the P-0327 fault a couple of times and it returns without the CEL ever coming on.
Do I need to be concerned about the P-0327 fault and have it checked, even though the car appears to be running normally and does NOT display a CEL? Removing the serpentine belt and alternator to get to the knock sensor may be more than I am willing to take on myself.
Thanks in advance for any feedback/recommendations.
