Code 22 - Knock Sensor No. 1 - R/H

NOTE: For ECM harness connector terminal identification, see Figure.
  1. Turn ignition on. Using a DVOM, check voltage between ECM harness connector terminal C5 (backprobe) and ground. Voltage should be 2-3 volts. If voltage is as specified, go to next step. If voltage is not as specified, check ECM harness connector terminals for good contact. Repair as necessary. If harness connector terminals are okay, replace ECM.
  2. Turn ignition off. Remove collector and disconnect knock sensor harness connector located on side of block. Using an ohmmeter, check resistance between knock sensor terminal and ground. Resistance should be about 560,000 ohms. If resistance is as specified, repair circuit between ECM and knock sensor. If resistance is not as specified, replace knock sensor.
