What does knock sensor 1 on Honda CRV mean?
Honda CR-V P0325: Knock Sensor “1” – Circuit Malfunction. P0325 is a powertrain OBDII trouble code that has the same meaning for the Honda CR-V as it would any other vehicle. By definition, it means that the vehicles ECM/PCM isn’t getting the proper signal to or from the knock sensor.
What causes a Honda CRV p0325 to knock?
Modern internal combustion engines utilize the knock sensor to allow for aggressive timing. If the timing has gotten too aggressive it’ll cause the engine to knock. This sensor will let the computer know to dial back the timing. The symptoms associated with P0325 are going to vary by engine and model year.
How much does it cost to fix a Honda knock sensor?
Most auto repairs shops charge between $75 and $150 per hour. When is the P0325 HONDA code detected? The Knock Sensor (KS) senses engine knocking (also known as detonation or pinging) using a piezoelectric element. The sensor is attached to the cylinder block, cylinder head or intake manifold.
Why is the knock sensor on my Honda Accord not working?
P0325 is telling you that the ECM/PCM is not getting the proper signal from the knock sensor. When this happens the computer will operate as though it is getting no signal from the sensor at all.

To me the most interesting part about the knock sensor is that it only has one wire going to it. The reason for this is the sensor generates its own voltage and is case grounded.
Can a bad knock sensor cause a check engine light to flash?
Usually a bad knock sensor will trigger the “check engine” light to flash on your vehicle’s dashboard.
