The CEL was on for about a week now, and the codes are P0131 & P0132, which points to the Primary Oxygen sensor. Some discussions on the internet indicates that if the wiring is touching the heat shield or manifold, which can cause a short, then the code may be triggered as well; since basically, it's shorted to GND.
On 3/21/2014, replaced the Oxygen sensor, and this fixed the problem.
Removed by: - Unplug the sensor connector
- Remove three 12mm bolts which hold the heat shield
- Use 7/8 wrench to remove the sensor
Install - Apply the anti-seize grease on the sensor thread
- Install the sensor by hand, then tight with the 7/8 wrench
- Install the heat-shield, and 3 bolts.
The sensor was bought from Autoplicity, Amazon for $48.78. DEN 234-4620. |
