Knock Sensors
Still need to fix these things. Got these codes!
I had replaced the stocks ones with a new harness. Going to order another factory harness and sensors this go around. If the problem still persist. I will assume some where it’s not properly grounded or somewhere maybe a wire is off. Smog check is coming up need to get these in working order again. Worked fine before I came along and broke something!
P0327 & P0332!

Excess AC ripple in the charging system “can” cause these 2 DTC’s to set...the knock sensors produce an AC voltage as do the wheel speed sensors...you can check AC ripple at the battery terminals with the DVOM set on AC...less than 50 Mv is OK (.05 volts)...you can also check resistance at the harness connector at each of the 2 wires to a good ground...93-107 Kilo ohms is good !!...buy OEM if replacing sensors and torque is CRITICAL !!...15 foot pounds !!...good luck !!
