What does this mean?
This diagnostic trouble code (DTC) indicates that the powertrain control module (PCM) has detected a problem with the knock sensor circuit for bank 1, sensor 1. The knock sensor is a device that detects engine knock and sends a signal to the PCM. The PCM uses this signal to adjust the engine's timing and fuel injection to prevent engine damage.
What are the symptoms of this code?
* The engine may run rough or stall.
* The engine may ping or knock.
* The check engine light may be illuminated.
What are the causes of this code?
* Faulty knock sensor
* Damaged or loose wiring to the knock sensor
* Faulty PCM
How is this code diagnosed?
A technician will use a scan tool to retrieve the trouble codes from the PCM. The technician will then inspect the knock sensor and wiring for damage. The technician may also test the knock sensor circuit with a multimeter.
How is this code fixed?
The technician will replace the knock sensor or repair the wiring if necessary. The technician will then clear the trouble codes from the PCM.
What is the cost to fix this code?
The cost to fix this code will vary depending on the cause of the problem. If the knock sensor is faulty, the cost will be around $100. If the wiring is damaged, the cost will be around $50. If the PCM is faulty, the cost will be around $500.
