  Q: How to replace the knock sensor on Mitsubishi Galant?

  A:

  This procedure only applies to models equipped with a V6 engine and 2.4L DOHC engine. The knock control system suppresses spark knock during heavy detonation to optimize spark advance for improved driveability. The knock sensor detects abnormal engine vibrations, sending a voltage signal to the PCM which increases in response to knock severity. The signal prompts the PCM to retard ignition until knock ceases. On V6 models, the intake manifold cover conceals the knock sensor. Make sure the ignition key is set to OFF. For V6 coded models the cooling system must be drained and the intake manifold removed. For 2.4L DOHC coded models the intake manifold stay must be removed. Unplug the knock sensor connector then unbolt the knock sensor. In case the old sensor were to be reused, thread sealant should be applied. New sensors come pre-coated with sealant so none should be put on. Put the knock sensor in place. Tighten the knock sensor to the required torque; do not overtighten. Then, connect the electrical connector. On V6 models, the intake manifold is reinstalled; On 2.4L DOHC models, the intake manifold stay is reinstalled. Lastly, on V6 models, refill cooling system and check for leaks.
