Knock sensor bank 2. Port or Starboard side?


Recommended Posts

shelbydog25

Changed the oil today on my 08 23LSV.  Had not removed the knock sensor yet for winterization. After a test drive   I got an SPN 65552 fault code which I think is for knock sensor bank 2.  Which side is bank 2 on for the Indmar 340?  Port or Starboard   
note: I removed the sensor on port side to finish the winterization and am still getting them same fault code

Diagnostic Aids
 • Inspect the KS for physical damage.
 • Inspect the KS for proper installation. A KS that is loose or over-torque may cause a DTC to set. The KS should be 
free of thread sealant.
 • The KS mounting surface should be free of burs, casting flash and, foreign material.
 • This test procedure requires that the vehicle battery has passed a load test and is completely charged.
 • When disconnecting electrical connectors or removing fuses and relays from a fuse block, always inspect the 
component electrical terminals for corrosion, and the mating electrical terminals for tightness.

Circuit/System Verification
1. Disconnect both KS electrical connectors.
2. Connect one test lead from the DMM to the signal circuit terminal on the KS, and the other test lead form the DMM to 
the low reference circuit terminal on the KS.
3. Set the DMM to the 400 mV AC hertz scale, and wait for the DMM to stabilize at 0 Hz.
Important: DO NOT tap on plastic engine components.
4. Tap on the engine block with a non-metallic object near the KS while observing the Hz signal indicated on the DMM 
display.
5. The DMM should display a fluctuating frequency while tapping on the engine block.
6. Repeat the above procedure for the KS on the opposite side of the engine block.
If the vehicle passes the Circuit/System Verification test, operate the vehicle within the Conditions for Running the DTC. 
The other option is to refer to Testing for Intermittent Conditions and Poor Connections.

Circuit/System Testing
SPN 65551 and 65552 FMI 2
1. Turn OFF the ignition.
2. Disconnect the KS electrical connector.
3. Measure for infinite resistance between the signal circuit terminal at the KS, and to a good engine ground, with a DMM.
If continuity is detected on the signal circuit, replace the KS.
5. Measure for infinite resistance between the low reference circuit terminal at the KS and to a good engine ground with a 
DMM.
If continuity is detected on the low reference circuit, replace the KS.
7. Turn ON the ignition, with the engine OFF.
8. Measure for voltage at the KS signal circuit terminal, on the wire harness electrical connector, for the KS.
If the KS signal circuit measures more than 4.2 volts, test for a short to voltage or a faulty ECM.
10. Measure for voltage at the KS low reference circuit terminal, on the wire harness electrical connector, for the KS.
If the KS low reference circuit measures more than 4.2 volts, test for a short to voltage, or a faulty ECM.
12. Test the KS signal circuit and the KS low reference circuit for the following conditions:
 • An open
 • A short to ground
 • High resistance—All wire circuit resistance must measure less than 5 ohms.
If the KS and wire circuits test normal, replace the ECM.
