Delphi AS10329 ignition knock (detonation) sensor for the 2011-2012 Ram 1500 V6 3.7L or V8 4.7L and other vehicles detects engine knock and sends a signal to the engine computer. The sensor is tested and calibrated to OE standards for accurate readings.
- Knock detection that helps protect the engine from damage caused by pre-ignition knocking
- Delphi knock sensor helps maximize engine performance with all fuels
- Sensor calibrated for a wide variety of frequencies to detect shifts and give accurate signals
- Sensor sealed to withstand humidity, salt spray and automotive fluids
- Ground isolated design with a 2 wire shielded harness that helps protect the signal from electromagnetic interference (EMI)
- Self generating piezoelectric design that requires no power to the sensor
Quick facts
- Part: Delphi AS10329 ignition knock (detonation) sensor
- Fits: 2011-2012 Ram 1500 V6 3.7L or V8 4.7L and other vehicles
- Condition: New
A failing knock sensor can set a check engine light, let the engine ping or leave it feeling down on power. These signs alone do not prove the sensor is the problem, since a damaged wiring connector can cause them too.
Fits
This knock sensor is a direct-fit replacement for the 2011-2012 Ram 1500 V6 3.7L or V8 4.7L, the 2008-2010 Dodge Ram 1500 V6 3.7L and the 2009-2010 Dodge Ram 1500 V8 4.7L, and the 2008-2010 Jeep Grand Cherokee V6 3.7L and the 2009 Grand Cherokee V8 4.7L. It also fits many other vehicles. This listing is one sensor: the 2008-2010 Dodge Ram 1500 V6 3.7L takes two, while the 2009-2010 Dodge Ram 1500 V8 4.7L takes one.

Frequently Asked Questions
Is the Delphi AS10329 knock sensor right for a 2011-2012 Ram 1500 V6 3.7L or V8 4.7L?
Yes, Delphi AS10329 fits the 2011-2012 Ram 1500 V6 3.7L and V8 4.7L, and each takes one sensor. If your car is not named here, look it up in the "Vehicles it fits" section.
Does the Delphi knock sensor need external power to work?
No. The self generating piezoelectric design requires no power to the sensor, and the 2 wire shielded harness helps protect its signal from electromagnetic interference (EMI).
Does the AS10329 knock sensor come as a single sensor?
Yes. Delphi AS10329 is sold as one ignition knock (detonation) sensor, and the package contents list nothing else.
What can a worn knock sensor look like on the road?
A worn or failing knock sensor can set a check engine light, let the engine ping, or lead to weaker performance. A shop can read the stored codes to narrow it down.
Does this Delphi sensor replace the KS191 knock sensor?
Yes. KS191 is one of the numbers on the interchange list for Delphi AS10329, so this sensor can stand in for it.
