PINPOINT TEST G258127p15 : DTC P0327, P0328; RIGHT-HAND KNOCK SENSOR (KS) HIGH/LOW VOLTAGE

G258127t53 : CHECK KS SENSING CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the battery negative terminal.
2. Disconnect the KS electrical connector, PI20.
3. Disconnect the ECM electrical connector, PI01.
4. Measure the resistance between PI20, pin 02 (N) and PI01, pin 98 (N).

- Is the resistance greater than 5 Ohms?

->YES
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.

->NO
GO to Pinpoint Test G258127t54.

G258127t54 : CHECK KS SENSING CIRCUIT FOR SHORT TO HIGH VOLTAGE
1. Turn the ignition switch to the ON position.
2. Reconnect the battery negative terminal.
3. Measure the voltage between PI20, pin 02 (N) and GROUND.

- Is the voltage greater than 5 volts?

->YES
REPAIR the short circuit to high voltage. CLEAR the DTC. TEST the system for normal operation.

->NO
GO to Pinpoint Test G258127t55.

G258127t55 : CHECK KS SENSING CIRCUIT FOR SHORT TO GROUND
1. Turn the ignition switch to the OFF position.
2. Measure the resistance between PI20, pin 02 (N) and GROUND.

- Is the resistance less than 10,000 Ohms?

->YES
REPAIR the short circuit to GROUND. CLEAR the DTC. TEST the system for normal operation.

->NO
GO to Pinpoint Test G258127t56.

G258127t56 : CHECK KS GROUND CIRCUIT FOR HIGH RESISTANCE
1. Measure the resistance between PI20, pin 01 (B) and PI01, pin 100 (BG).

- Is the resistance greater than 5 Ohms?

->YES
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.

->NO
INSTALL a new KS. CLEAR the DTC. TEST the system for normal operation.
