Delphi AS10334 ignition knock (detonation) sensor for the 2000-2004 Toyota Tundra V8 4.7L and other vehicles senses engine knock and sends a signal to the engine computer. Delphi sensors are tested and calibrated to OE standards, which helps give accurate readings.
- Knock sensor helps maximize engine performance with all fuels
- Knock sensor is designed to protect the engine from damage caused by pre-ignition knocking
- Sensor is calibrated for a wide variety of frequencies to detect shifts and give accurate signals
- Sensor is sealed to withstand humidity, salt spray and automotive fluids
- Ground-isolated design with a 2-wire shielded harness helps protect the signal from electromagnetic interference (EMI)
- Self-generating piezoelectric design requires no power to the sensor
Quick facts
- Part: Delphi AS10334 ignition knock (detonation) sensor
- Fits: 2000-2004 Toyota Tundra V8 4.7L and other vehicles
- Condition: New
A check engine light, pinging under load or a loss of power can mean this sensor is wearing out. Those signs alone do not prove the sensor is at fault, since a damaged wiring connector can produce them too.
Fits
The 2000-2004 Toyota Tundra V8 4.7L, the 2003-2004 Toyota 4Runner V8 4.7L and the 2001-2004 Toyota Sequoia V8 4.7L are among the vehicles this sensor fits. If your Toyota or Lexus is not one of those, look up its year, model and engine in the "Vehicles it fits" section. This listing is one sensor, and the 2000-2004 Toyota Tundra V8 4.7L takes two.

Frequently Asked Questions
Does the Delphi AS10334 knock sensor fit the 2000-2004 Toyota Tundra V8 4.7L?
Yes. Delphi AS10334 fits the 2000-2004 Toyota Tundra V8 4.7L, and it also fits the 2003-2004 Toyota 4Runner V8 4.7L.
Does this knock sensor need power to work?
No. Its self-generating piezoelectric design means no power goes to the sensor.
Is the Delphi AS10334 knock sensor sealed against salt spray and fluids?
Yes. The Delphi AS10334 is sealed against humidity, salt spray and automotive fluids.
What does the shielded harness on this knock sensor do?
The 2-wire harness is shielded and the sensor is ground isolated, which helps keep electromagnetic interference (EMI) from disturbing its signal.
Does Delphi AS10334 replace the 89615-52010 knock sensor?
Yes. 89615-52010 is on the interchange list for the Delphi AS10334 sensor.
