P0552 1997 Ford F150 Code - Power Steering Pressure Sensor Circuit Malfunction

Quick Answer

Power steering pressure (PSP) sensor is installed to the power steering high-pressure tube and detects a power steering load. Common causes include Faulty Power Steering Pressure Sensor, Power Steering Pressure Sensor harness is open or shorted, Power Steering Pressure Sensor circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0552 1997 Ford F150 Description

Power steering pressure (PSP) sensor is installed to the power steering high-pressure tube and detects a power steering load. This sensor is a potentiometer which transforms the power steering load into output voltage, and emits the voltage signal to the Engine Control Module (ECM). The ECM controls the electric throttle control actuator and adjusts the throttle valve opening angle to increase the engine speed and adjusts the idle speed for the increased load.

Frequently Asked Questions about P0552 1997 Ford F150 Code

1. What does OBDII code P0552 mean on a 1997 Ford F150?

Code P0552 indicates a malfunction in the Power Steering Pressure (PSP) sensor circuit, specifically a low voltage signal being sent to the ECM.

2. What are the common symptoms of code P0552?

Symptoms may include a check engine light, heavy steering at low speeds, reduced fuel efficiency, or erratic engine idle during steering.

3. What causes the P0552 code on a Ford F150?

Possible causes include a faulty PSP sensor, damaged wiring or connectors in the PSP circuit, low power steering fluid, or a malfunctioning ECM.

4. Can I still drive my 1997 Ford F150 with the P0552 code?

Yes, you can typically drive with this code, but ignoring it may lead to reduced performance, steering difficulties, or potential damage to related components over time.

5. How do I diagnose the P0552 code?

Start by checking the power steering fluid level, inspecting the PSP sensor and its wiring for damage, and using a multimeter to test the sensor's voltage output.

6. How do I fix the P0552 code on my Ford F150?

Repairs may involve replacing the PSP sensor, repairing damaged wiring or connectors, refilling power steering fluid, or, in rare cases, replacing the ECM.

7. Where is the Power Steering Pressure sensor located on a 1997 Ford F150?

The PSP sensor is typically located on the power steering pressure line near the steering pump.

8. How much does it cost to fix code P0552 on a Ford F150?

The cost can range from $50 to $200, depending on whether you need to replace the sensor, repair wiring, or address other related issues.

9. Will clearing the P0552 code fix the issue?

Clearing the code will turn off the check engine light temporarily, but the underlying problem must be fixed to prevent the code from returning.

10. Can low power steering fluid trigger the P0552 code?

Yes, low power steering fluid can cause abnormal pressure readings, potentially triggering the code. Always check fluid levels as part of your diagnosis.
