The P0553 OBD-II code indicates a problem with the power steering pressure sensor or switch circuit. This code is flagged when the vehicle’s onboard diagnostic system detects an issue with the signal from the power steering pressure sensor, which is crucial for maintaining the proper idle speed of the engine while navigating at low speeds.
What Does the P0553 Code Mean?
The P0553 code is defined as a “Power Steering Pressure Sensor/Switch Circuit High.” It indicates that the power steering pressure sensor is sending a voltage signal that is higher than expected to the Powertrain Control Module (PCM). This signal is necessary for the PCM to adjust the engine’s idle speed during low-speed maneuvers.
What Causes the P0553 Code?
Several factors can trigger the P0553 code, including:
- Power steering pressure sensor failure
- Powertrain Control Module (PCM) failure
- Wiring issues, such as damaged or corroded connectors
What Are the Symptoms of the P0553 Code?
Common symptoms associated with the P0553 code include:
- Engine may stall when pulling into a parking spot
- Difficulty steering at low speeds
- Illuminated check engine light
How Serious Is the P0553 Code?
The severity of the P0553 code is considered moderate. While it may not pose an immediate threat to the vehicle’s safety or functionality, it is essential to have it diagnosed and repaired in a timely manner to prevent further issues and maintain optimal vehicle performance.
How to Diagnose the P0553 Code
Diagnosing the P0553 code typically involves the following steps:
- Use an OBD-II scanner to confirm the presence of the P0553 code.
- Inspect the power steering pressure sensor and its wiring for any signs of damage or corrosion.
- Check the voltage reading from the power steering pressure sensor to ensure it is within the manufacturer’s specifications.
- Test the Powertrain Control Module (PCM) for proper function, if necessary.
Common Repairs for the P0553 Code
Some common repairs that may be required to resolve the P0553 code include:
- Replacing the power steering pressure sensor
- Repairing or replacing damaged wiring or connectors
- Reprogramming or replacing the Powertrain Control Module (PCM)
How Much Does It Cost to Fix the P0553 Code?
The cost to fix the P0553 code can vary widely depending on the specific repairs needed. On average, you can expect:
- Power steering pressure sensor replacement: $100 to $300
- Wiring repairs: $50 to $200
- PCM replacement or reprogramming: $300 to $1,000
Can I Fix the P0553 Code Myself?
While some DIY enthusiasts may be able to diagnose and replace a faulty power steering pressure sensor or repair wiring issues, it is recommended that you seek professional assistance for complex repairs, such as PCM replacement or reprogramming, to ensure proper resolution of the P0553 code.
