Delphi AS10312 ignition knock (detonation) sensor for the 2005-2014 Volkswagen Jetta 5-cylinder 2.5L, the 2010 Jetta 4-cylinder 2.0L and other vehicles detects engine knock and sends a signal to the engine computer. The engine computer uses that signal to respond to knock.
- Helps maximize engine performance with all fuels
- Helps prevent engine damage from pre-ignition knocking
- Calibrated for a wide variety of frequencies to detect shifts and give accurate signals
- 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 AS10312 ignition knock (detonation) sensor
- Fits: the 2005-2014 Volkswagen Jetta 5-cylinder 2.5L, the 2010 Jetta 4-cylinder 2.0L and other vehicles
- Condition: New
Before you replace this sensor, rule out a damaged harness or connector and other causes of the same symptoms, since a check engine light, pinging under load or a drop in power can come from several parts. If a failed knock sensor is the cause, this one replaces it.
Fits
The vehicles it fits include the 2012-2014 Volkswagen Passat 5-cylinder 2.5L and the 2010-2014 Volkswagen Golf 5-cylinder 2.5L. This listing is one sensor, and the 2012-2014 Volkswagen Passat 5-cylinder 2.5L takes one. Open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Does the Delphi AS10312 knock sensor fit a 2010 Volkswagen Jetta 4-cylinder 2.0L?
Yes. Delphi AS10312 is listed for the 2010 Volkswagen Jetta 4-cylinder 2.0L and for the 2005-2014 Volkswagen Jetta 5-cylinder 2.5L. Open the "Vehicles it fits" section to check other models.
Does a self-generating piezoelectric knock sensor like the Delphi AS10312 need power?
No. Delphi AS10312 has a self-generating piezoelectric design, so it requires no power to the sensor.
Is this Delphi knock sensor sealed against road salt and moisture?
Yes. This knock sensor is sealed to withstand humidity, salt spray and automotive fluids.
What kind of harness does this knock sensor have, and does it resist interference?
It has a ground isolated design with a 2-wire shielded harness, which helps protect the sensor signal from electromagnetic interference (EMI).
Does Delphi AS10312 replace the number 07K 905 377 B?
Yes. 07K 905 377 B is one of the numbers this sensor replaces; the Interchange line on this page lists the others.
