Code P1152 1997 Ford F150 Description
The diagnostic trouble code P1152 on a 1997 Ford F150 indicates a lack of upstream heated oxygen sensor switch sensor indicating a rich condition on Bank 2 of the engine. The upstream heated oxygen sensor, also known as the O2 sensor, is responsible for monitoring the oxygen level in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. In this case, the sensor is detecting a rich air-fuel mixture on Bank 2, which means there is an excess of fuel in the exhaust gases.
Common Causes of P1152 1997 Ford F150
- Faulty upstream heated oxygen sensor on Bank 2
- Vacuum leak in the intake system
- Malfunctioning fuel injector on Bank 2
- Issue with the fuel pressure regulator
- Air intake system problem on Bank 2
Symptoms of P1152 1997 Ford F150
- Decreased fuel efficiency
- Reduced engine power
- Rough idle or stalling
- Check Engine Light illuminated
- Increased emissions
