What does DTC stand for on knock sensor?
Diagnostic trouble code (DTC) P0327 stands for “Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor).” It is triggered when the powertrain control module (PCM) detects very low voltage readings from your vehicle’s primary knock sensor circuit.
What is the DTC code for a Sierra 1500?
DTC P0117 Engine Coolant Temperature (ECT) Sensor Circuit Low Voltage in Engine Controls – 4.3L or 4.8L, 5.3L, 6.0L DTC P0118 Engine Coolant Temperature (ECT) Sensor Circuit High Voltage in Engine Controls – 4.3L or 4.8L, 5.3L, 6.0L
Why is the knock sensor on my GMC Sierra not working?
It would be wise to start by taking a look at the wiring harness. P0332 is telling you that the ECM/PCM is getting a low signal from the knock sensor. When this happens the computer will operate as though it is getting no signal from the sensor at all. Check the wiring leading from the sensor and see if any of it has been damaged or frayed.
What is the DTC code for a Chevy Silverado?
DTC P1107 Manifold Absolute Pressure (MAP) Sensor Circuit Intermittent Low Voltage DTC P1111 Intake Air Temperature (IAT) Sensor Circuit Intermittent High Voltage DTC P1112 Intake Air Temperature (IAT) Sensor Circuit Intermittent Low Voltage DTC P1114 Engine Coolant Temperature (ECT) Sensor Circuit Intermittent Low Voltage
DTC P0117 Engine Coolant Temperature (ECT) Sensor Circuit Low Voltage in Engine Controls – 4.3L or 4.8L, 5.3L, 6.0L DTC P0118 Engine Coolant Temperature (ECT) Sensor Circuit High Voltage in Engine Controls – 4.3L or 4.8L, 5.3L, 6.0L
Are there any knock sensor related DTC codes?
Other knock sensor related DTC codes include P0325, P0326, P0327, P0328, P0329, P0330, P0331, P0333, and P0334. You may notice drivability problems including fluctation engine RPM, a loss of power, and perhaps some hesitation. There may also be other symptoms. Potential causes for a P0332 DTC include (but are not limited to):
What does the knock sensor on a Chevy Silverado do?
The amount of AC voltage that the knock sensor produces is proportional to the amount and strength of the engine knock. Once your Chevrolet Silverado or GMC Sierra’s fuel injection computer receives the knock sensor’s signal, it’ll then retard ignition timing to reduce/eliminate the engine knock.
Why is my knock sensor on Bank 2 low?
If your knock sensor on Bank #2 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0332 DTC. This P0332 code may show up intermittently or the Service Engine light may be lit constantly.
