Code P1152 2002 Ford F150 Description
The diagnostic trouble code P1152 for a 2002 Ford F150 indicates a lack of response 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 2002 Ford F150
- Failed upstream heated oxygen sensor on bank 2
- Wiring or connector issues related to the oxygen sensor
- Exhaust leaks near the oxygen sensor
- Vacuum leaks affecting the oxygen sensor readings
- Internal engine problems affecting combustion efficiency on bank 2
Symptoms of P1152 2002 Ford F150
- Decreased fuel efficiency
- Rough idling or stalling
- Engine misfires
- Check Engine Light illuminated
- Strong fuel odor from the exhaust
How to Fix P1152 2002 Ford F150
- Begin by diagnosing the issue using a scan tool to confirm the P1152 code and check live data from the oxygen sensors.
- Inspect the wiring and connectors leading to the upstream HO2S on bank 2 for any damage or corrosion. Repair or replace as necessary.
- Check for exhaust leaks near the oxygen sensor and repair them to ensure accurate readings.
- Test the oxygen sensor itself for proper function using a multimeter or oscilloscope. Replace the sensor if it fails to respond correctly.
- Clear the trouble code from the ECM's memory and perform a test drive to verify that the issue has been resolved.
Cost to Fix P1152 2002 Ford F150
The cost of repairing a lack of response from the upstream heated oxygen sensor on bank 2 in a 2002 Ford F150 can vary depending on the specific cause of the issue. On average, the cost of replacing an oxygen sensor ranges from $100 to $300, including parts and labor. Additional costs may apply if wiring repairs or other components need attention. It's recommended to consult with a trusted mechanic or dealership for a more accurate estimate based on your vehicle's specific needs and location. Labor rates can vary between $80 and $150 per hour, so it's advisable to inquire about local rates before proceeding with the repair.
