Code P1152 2001 Ford F150 Description
The diagnostic trouble code P1152 for a 2001 Ford F150 indicates a lack of activity from the upstream heated oxygen sensor (HO2S) on bank 2, which is typically the side of the engine that does not contain cylinder 1. The upstream HO2S is responsible for monitoring the oxygen content in the exhaust gases before they enter the catalytic converter. This information is crucial for the engine control module (ECM) to adjust the air-fuel mixture to achieve optimal combustion efficiency.
Common Causes of P1152 2001 Ford F150
- Faulty upstream HO2S on bank 2
- Wiring or connector issues in the oxygen sensor circuit
- Exhaust leaks near the sensor
- Vacuum leaks in the intake system
- Fuel system issues, such as a clogged fuel injector
Symptoms of P1152 2001 Ford F150
- Decreased fuel efficiency
- Rough idle or stalling
- Engine misfires
- Check Engine Light illuminated
- Increased emissions output
How to Fix P1152 2001 Ford F150
- Use an OBD-II scanner to confirm the P1152 code and identify the specific upstream HO2S on bank 2.
- Inspect the wiring and connector for any damage or corrosion, repairing or replacing as needed.
- Check for exhaust leaks near the sensor and repair them if present.
- Perform a visual inspection of the intake system for vacuum leaks and address any leaks found.
- Test the fuel injector on bank 2 for proper operation and replace if necessary.
Cost to Fix P1152 2001 Ford F150

Frequently Asked Questions about P1152 2001 Ford F150 Code
1. What does the OBDII code P1152 mean on a 2001 Ford F150?
Code P1152 indicates that the upstream heated oxygen sensor (HO2S) on Bank 2 is detecting a consistently rich air-fuel mixture and isn’t switching as expected.
2. What are the symptoms of code P1152 on a 2001 Ford F150?
Symptoms may include poor fuel economy, rough idling, black smoke from the exhaust, hesitation during acceleration, and the check engine light being illuminated.
3. What causes code P1152 on a 2001 Ford F150?
Common causes include a faulty upstream oxygen sensor (Bank 2), a vacuum leak, a malfunctioning fuel injector, excessive fuel pressure, or issues with the powertrain control module (PCM).
4. How do I fix the P1152 code on my 2001 Ford F150?
Repairs may involve replacing the upstream oxygen sensor on Bank 2, checking for vacuum leaks, inspecting fuel injectors, or addressing fuel system issues like high fuel pressure.
5. Can a dirty or damaged mass airflow (MAF) sensor cause code P1152?
Yes, a faulty MAF sensor can send incorrect air-flow readings to the PCM, causing a rich condition and triggering the P1152 code.
6. Is it safe to drive with the P1152 code on a 2001 Ford F150?
While it may be safe to drive short distances, prolonged driving with this code can lead to engine damage, poor fuel efficiency, and excessive emissions. Prompt diagnosis and repair are recommended.
7. How can I diagnose a P1152 code on my 2001 Ford F150?
Start by scanning the code, inspecting the upstream oxygen sensor (Bank 2), checking for vacuum leaks, testing the fuel injectors, and verifying the fuel pressure.
8. Does the P1152 code always mean the oxygen sensor is faulty?
No, while a faulty oxygen sensor is a common cause, issues like fuel delivery problems, vacuum leaks, or PCM errors can also trigger the code.
9. How much does it cost to repair a P1152 code on a 2001 Ford F150?
Repair costs vary, but replacing an oxygen sensor typically costs $150-$300, while addressing other issues like vacuum leaks or fuel system problems may increase costs.
10. Which side of the engine is Bank 2 on a 2001 Ford F150?
On a 2001 Ford F150, Bank 2 is located on the passenger side of the engine.
