Many people complain about the P132B code on their 6.7 Powerstroke engine. However, Ford super-duty trucks have high-performance and reliable engines.
What is P132B Code on 6.7 Powerstroke? P132B code on 6.7 Powerstroke is due to exhaust leakage, turbocharger defects, broken intake seals, malfunctioning EGR valve, and faulty manifold absolute pressure sensor. Its symptoms are turbo sounds, check light, reduced engine efficiency, and low horsepower.
Several internal engine failures can trigger this error code. However, malfunctioning turbochargers and faulty exhaust systems are significant reasons.
What are the causes of the P132B code on 6.7 Powerstroke?
Many factors can cause this P132B codes on a durable 6.7L Powerstroke. However, I have explained a few of them below.
Leakage of the exhaust system
This engine has an exhaust gas reticulation system (EGR) for regulating gases and hydrocarbons. However, the exhaust gas reticulation system has a specific valve.
It has an inlet, durable, and insulated pipe. The malfunctioning exhaust reticulation system valve triggers this error code.
The EGR valve fasteners lose their connecting points and malfunction. In such circumstances, the fastener cannot stabilize the bracket and pipe according to standard working conditions.
The malfunctioning EGR valve causes this code and shows the reduced performance of the truck. The motor efficiency reduces, and the hood temperature increases beyond limitations.
The high temperature can break the EGR actuator. In such circumstances, the exhaust vacuum line malfunctions.
The loose fastener can cause cracking of the seals. As a result, the exhaust system undergoes leakage and generates the P132B code on the dashboard of the pickup truck.
The exhaust reticulation valve of the 6.7-liter Powerstroke malfunctions and cannot regulate the temperature level of the combustion cylinders due to its damage.
External pressure, heat, and dust can damage this valve. The level of nitrogen oxides increases over time.
However, the accumulation of deposits can damage this valve, which leads to reduced horsepower. The malfunctioning EGR valve can reduce acceleration, internal motor power, and fuel efficiency.
The emissions increase and lead to reduced fuel economy of the pickup truck.
Defects of turbocharger
This engine has a specific turbocharger which comprises the turbine wheel and a compressor. Moreover, it has a shaft that can regulate the intake pressure of the air.
The turbo can draw power from the gases of the exhaust system. The gases increase the compressor strain to reduce friction.
Also, it increases the motor’s horsepower. As a result, the emissions decrease, and hydrocarbons do not evaporate into the environment.
Dust can contaminate the oil, and its flow reduces. In such circumstances, it cannot flow at the standard viscosity level.
The engine lacks oil, and the turbocharger malfunctions. The clogging of flow pipelines and internal components can damage the turbocharger.
The contaminated oil can crack the bearing of the exhaust system and turbocharger of the 6.7L Powerstroke malfunctions.
The variable geometry turbocharger solenoid breaks and triggers the P132B code on the dashboard.
The reduced oil flow decreases its pressure to the lowest levels. In such circumstances, the motor cannot facilitate standard efficiency.
Broken seals of intake
The intakes are vital and reliable components of a 6.7-liter Powerstroke on Ford super-duty trucks. In addition, it can bring external air inside the engine due to its standard mechanism.
The intakes carry out combustions and increase truck efficiency. In addition, it can pull oxygen to the combustion cylinder and causes more air and fuel burns.
It can increase the horsepower of the motor with optimized and stable combustion. The engine torque enhances when the intakes work efficiently.
Debris and dirt accumulate on the air intake vents. As a result, the throttle cannot perform, and torque reduces from the standard limitations.
The crankcase of the engine has vents that undergo clogging.
Faulty Manifold absolute pressure sensor
The high-performance 6.7-liter Powerstroke has a manifold absolute pressure sensor. It is an electric sensor that connects with a hose.
The heat and strain can damage the hose and causes leakage. In addition, the fast driving conditions for several hours and excessive vibrations can damage the sensors.
The sensor loses its connection and malfunctions. The defective manifold absolute pressure sensor cannot calculate the air and fuel mixing.
It cannot determine the fuel level for proper injection. This is because the internal pressure value of the manifold absolute pressure sensor increases from the suggested pressure.
The higher value can cause defects in the MAP sensor. It’s malfunctioning connectors and broken wires reduce its efficiency.
What are the symptoms of the P132B code on 6.7 Powerstroke?
Several mechanical and technical failures indicate the symptoms of the P132B code.
Turbo produces sounds
Exhaust gases can regulate the turbo of a 6.7-liter Powerstroke. However, the O132B code appears and indicates the defects of this turbocharger.
In such circumstances, the turbo produces loud audible sounds. The sound volume increases at fast speed levels.
Broken turbo bearing and contamination of oil reduce the performance of this turbocharger. It cannot produce more torque, and horsepower reduces.
The reduced torque affects truck speed.
P132B is an OBD-II code and illuminates the check engine light. In such circumstances, the warning light shows the defects of the 6.7-liter Powerstroke and its exhaust system.
It indicates higher emissions and reduces EGR valve performance. The warning light and code illuminate to indicate the defects.
The illumination of the engine check light indicates the defects of the motor and its connected parts. It shows the modified combustions which affect acceleration.
Reduced engine horsepower
The dirt particles contaminate the oil and reduce its efficiency.
The dirt and contaminated oil reduce the efficiency of the engine. In such circumstances, the horsepower of the engine reduces.
The reduced horsepower decreases the acceleration of the pickup truck. The speed reduction shows reduced engine efficiency and the lowest horsepower.
It is a sign of turbocharger defects and engine problems. Poor engine efficiency decreases the speed.
The internal engine failures cause a reduction in horsepower. The engine torque (rotations per minute) decreases.
The speed reduces from the standard limitations.
How to fix the P132B engine code on 6.7 Powerstroke?
You can fix the P132B code on your 6.7-liter Powerstroke by troubleshooting the internal effects of the turbocharger. Checking the exhaust reticulation system valve and sensor is essential for optimized troubleshooting.
You can inspect the exhaust leaks and broken seals. You can replace the broken turbocharger, which is a complicated procedure and requires professional assistance.
The downpipe connects with the turbocharger of the engine. Connecting a wrench and bolt puller is essential for all the bolts.
Rotating the wrench in a counterclockwise position is better for removing the bolts. Then, you can remove all the screws and pull the exhaust pipe.
It is better to remove the engine intake system to remove the turbo from this engine. You can adjust a wrench on the bolts and remove them from the connection points of the turbo and exhaust pipes.
Removing the intercooler is necessary because it makes the turbo visible. You can remove the old and malfunctioning turbo and add the new turbocharger.
You can change the EGR valve and remove the P132B code on the engine.
The EGR valve is near the cylinder head and connects to the exhaust manifold through a durable pipe. You can disconnect the truck battery and find the EGR valve in the hood.
Removing the vacuum hose improves valve visibility. You can remove the bolts from the valve and pull the valve.
Installing a compatible valve is better because it removes this error code and stabilizes horsepower. It reduces emissions and increases torque for better acceleration.
