Ignition Knock (Detonation) Sensor for 1999-2004 Nissan Frontier & More - NTK ID0138

NTK ID0138 ignition knock (detonation) sensor for the 1999-2004 Nissan Frontier V6 3.3L and other vehicles monitors engine vibration to help prevent detonation. A piezoelectric crystal generates a varying voltage based on vibration intensity, and that signal is used to delay the ignition timing.

• Piezoelectric crystal that produces a varying voltage with engine vibration intensity
• Reinforced components reduce the chance of part failure and prevent corrosion and moisture penetration
• Shielded harness prevents electrical interference

Quick facts

• Part: NTK ID0138 ignition knock (detonation) sensor
• Fits: 1999-2004 Nissan Frontier V6 3.3L and other vehicles
• Condition: New

Reasons to replace it include a check engine light, engine hesitation, poor fuel economy or a failed emissions test. These signs alone do not prove the sensor is at fault, since a worn spark plug can also make an engine hesitate.

Fits

The sensor is listed for a wide range of Nissan and Mercury models, led by the 2000-2004 Nissan Xterra V6 3.3L and the 1999-2002 Nissan Quest V6 3.3L, and each takes one sensor. This listing is one sensor. Driving something else? Look up your own year and engine in the "Vehicles it fits" section. It is built to meet or exceed OE fit, form and function.
