Nissan Maxima A32 A33 Knock Sensor Replacement and Self-Diagnostics Error 34
Is your Nissan Maxima no longer performing as well as it used to, especially after 2,500-3,000 rpm? Run a self-diagnosis and you'll likely find error code 34. This indicates that the knock sensor isn't adjusting the ignition timing to an advanced value, causing the car to run sluggishly and consume more fuel.
