first time poster here, long story short a good friend of mine gave me his 96 Nissan SE-R its 100% stock with 167K on the odometer. when i got it it had been sitting for a couple months and had a broken clutch release lever. i replaced the lever and the clutch assembly and started driving it. i plugged in a scan tool after a few days and i had a P0325 Knock sensor hi or low voltage. i checked the resistance of the sensor it was around 1000 ohms and spec is 500-600 ohms. my question is, this sensor is $170-200 and considering i got the car for free thats more than i want to spend on it. is there a cheaper source of a knock sensor or is there a way i can trick the ECU into thinking there is a knock sensor there. trying to get the car smoged and the code is keeping the monitors from running.
