P013E Saturn Code - HO2S Delay Response Rich to Lean Bank 1 Sensor 2
Quick Answer
The Heated Oxygen Sensors (HO2S) are used for fuel control and catalyst monitoring. Common causes include Faulty Heated Oxygen Bank 1 Sensor 2, Heated Oxygen Bank 1 Sensor 2 harness is open or shorted, Heated Oxygen Bank 1 Sensor 2 circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P013E Saturn Description
The heating elements inside each HO2S heat the sensor to bring the sensor up to operating conditions faster. This allows the system to enter Closed Loop earlier and the ECM to calculate the air-to-fuel ratio sooner.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the O2 sensor voltage has not decreased below 450 mV within a calibrated value of accumulated airflow.
What are the Possible Causes of the DTC P013E Saturn?
- Faulty Heated Oxygen Bank 1 Sensor 2
- Heated Oxygen Bank 1 Sensor 2 harness is open or shorted
- Heated Oxygen Bank 1 Sensor 2 circuit poor electrical connection
- Low or high fuel system pressure
- Fuel contamination
- Faulty fuel injectors
- Exhaust gas leaks
- Engine vacuum leaks
How to Fix the DTC P013E Saturn?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P013E Saturn Code
What does the OBDII code P013E mean on a Saturn?
P013E indicates that the ECM has detected a delayed response from the oxygen sensor (Bank 1 Sensor 2) when transitioning from a rich to a lean condition.
What are the symptoms of code P013E on a Saturn?
Common symptoms include an illuminated check engine light, reduced fuel efficiency, and possibly poor engine performance.
What causes the P013E code on a Saturn?
Potential causes include a faulty downstream oxygen sensor, exhaust leaks, wiring issues, or a malfunctioning ECM.
Can I drive my Saturn with a P013E code?
While the car may still be drivable, prolonged use with this code can lead to reduced fuel economy and potential damage to other emission control components.
How do I diagnose a P013E code on a Saturn?
Start by checking the oxygen sensor's wiring and connections, inspect for exhaust leaks, and use an OBDII scanner to monitor sensor performance.
How do I fix the P013E code on a Saturn?
Repairs may involve replacing the downstream oxygen sensor (Bank 1 Sensor 2), repairing wiring or connector issues, or addressing any exhaust leaks.
How much does it cost to fix the P013E code on a Saturn?
Replacing an oxygen sensor typically costs between $150 and $300, including parts and labor, but costs may vary based on the repair.
Can an exhaust leak cause the P013E code on a Saturn?
Yes, an exhaust leak can disrupt oxygen sensor readings, potentially triggering this code.
Is the P013E code related to emissions issues?
Yes, the code is directly related to the oxygen sensor, which plays a crucial role in monitoring and controlling emissions.
How can I prevent the P013E code from reoccurring on my Saturn?
Regular maintenance, ensuring proper sensor installation, and promptly addressing exhaust or wiring issues can help prevent this code.
