P1334 Ford Code - EGR Throttle Position Sensor Minimum Stop Performance
Quick Answer
The Exhaust Gas Recirculation (EGR) Throttle Position (EGRTP) Actuator modifies the air flow into the intake manifold by controlling a throttle plate within the throttle body. Common causes include Faulty Exhaust Gas Recirculation (EGR) Throttle Position (EGRTP) Actuator, EGRTP Actuator harness is open or shorted, EGRTP Actuator circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1334 Ford Description
The EGRTP sensor is a rotary position sensor. A 5-volt reference voltage supplied by the PCM, is utilized by the sensor to provide an input signal that is proportional to the angle of the throttle plate.
The Diagnostic Trouble Code (DTC) is set when the EGR Throttle Position closed position voltage is less than 3.83 volts or when the EGR Throttle Position open position is greater than 0.93 volts at initial Key on.
What are the Possible Causes of the DTC P1334 Ford?
- Faulty Exhaust Gas Recirculation (EGR) Throttle Position (EGRTP) Actuator
- EGRTP Actuator harness is open or shorted
- EGRTP Actuator circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
How to Fix the DTC P1334 Ford?
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.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P1334 Ford code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P1334 Ford Code
1. What does the OBDII code P1334 mean on a Ford vehicle?
P1334 indicates an issue with the EGR Throttle Position Sensor Minimum Stop Performance, meaning the sensor is not properly detecting the throttle stop position for the EGR system.
2. What are the common symptoms of a P1334 code on a Ford?
Symptoms may include poor engine performance, rough idling, hesitation during acceleration, reduced fuel efficiency, and possibly an illuminated check engine light.
3. What causes the P1334 code to appear on a Ford?
Common causes include a malfunctioning EGR throttle position sensor, wiring or connector issues, carbon buildup in the EGR system, or a faulty PCM (Powertrain Control Module).
4. Can I drive my Ford with a P1334 code?
While the vehicle may still run, driving with a P1334 code can lead to poor performance, increased emissions, and potential damage to the EGR system or other components over time.
5. How is the P1334 code diagnosed?
A technician will use an OBDII scanner to confirm the code, visually inspect the EGR components, test the throttle position sensor, check wiring and connectors, and possibly perform a smoke or vacuum test for leaks.
6. How do I fix the P1334 code on my Ford?
Repairs may include cleaning or replacing the EGR throttle position sensor, repairing damaged wiring or connectors, cleaning the EGR system to remove carbon buildup, or reprogramming the PCM if necessary.
7. How much does it cost to repair a P1334 code on a Ford?
Costs vary depending on the specific issue but typically range from $150 to $500, including parts and labor, with sensor replacement being on the lower end and PCM reprogramming or replacement on the higher end.
8. Can a dirty EGR valve cause the P1334 code?
Yes, carbon buildup in the EGR valve or related passages can interfere with the throttle position sensor's ability to detect the correct minimum stop position.
9. How can I prevent the P1334 code from recurring?
Regular maintenance, including cleaning the EGR system and inspecting the throttle position sensor and wiring for damage, can help prevent the code from recurring.
10. Will a faulty PCM always trigger the P1334 code?
Not always, but if the sensor and wiring are in good condition, the PCM could be the root cause and may require reprogramming or replacement.
