As a car expert, I understand how frustrating it can be to encounter a fault code on your vehicle. One of the most common codes that car owners face is the P1473 SSPOD Open Circuit or Closed Circuit Fault. This code indicates that there is an issue with the Secondary Speed Sensor Output Circuit. In this article, I will provide you with a step-by-step guide on how to fix this issue.
What is the P1473 SSPOD Open Circuit or Closed Circuit Fault?
The Secondary Speed Sensor Output Circuit is responsible for providing the Engine Control Module (ECM) with information about the speed of the transmission output shaft. The ECM uses this information to determine the appropriate shift points for the transmission. When the P1473 code appears, it means that there is an issue with the SSPOD circuit, which can be either an open or closed circuit fault.
Step-by-Step Guide to Fixing the P1473 SSPOD Open Circuit or Closed Circuit Fault
Step 1: Check the Wiring
The first step in fixing the P1473 code is to check the wiring. Start by inspecting the wiring harness for any signs of damage or wear. Look for any frayed wires, loose connections, or corroded terminals. If you find any issues, repair or replace the wiring as necessary.
Step 2: Check the Sensor
Next, check the Secondary Speed Sensor for any signs of damage or wear. Look for any cracks, chips, or other damage. If you find any issues, replace the sensor.
Step 3: Check the ECM
If the wiring and sensor are both in good condition, the issue may be with the ECM. Use a scan tool to check for any other fault codes that may be present. If there are no other codes, the ECM may need to be replaced.
Step 4: Clear the Code
Once you have fixed the issue, clear the P1473 code from the ECM using a scan tool. This will reset the system and allow the transmission to shift properly.
Useful Tips for Fixing the P1473 SSPOD Open Circuit or Closed Circuit Fault
Tip 1: Always disconnect the battery before working on any electrical components in your vehicle.
Tip 2: Use a multimeter to test the wiring and sensor for continuity and resistance.
Tip 3: If you are unsure about any of the steps in this guide, consult a professional mechanic.
Conclusion
The P1473 SSPOD Open Circuit or Closed Circuit Fault can be a frustrating issue to deal with, but with the right tools and knowledge, it can be fixed. By following the step-by-step guide provided in this article, you can diagnose and repair the issue yourself. Remember to always take safety precautions when working on your vehicle and consult a professional if you are unsure about any of the steps.
