Code P1553 Volkswagen Description
The P1553 diagnostic trouble code for Volkswagen vehicles indicates that the barometric/manifold pressure signal ratio is out of range. This means that there is a discrepancy between the barometric pressure sensor and the manifold pressure sensor readings, which can lead to incorrect fuel delivery and combustion timing. The barometric pressure sensor measures the atmospheric pressure outside the engine, while the manifold pressure sensor measures the pressure inside the intake manifold. When the ratio between these two readings deviates from the expected range, it can cause performance issues in the vehicle.
Common Causes of P1553 Volkswagen
- Faulty barometric pressure sensor
- Malfunctioning manifold pressure sensor
- Vacuum leak in the intake system
- Clogged air filter
- Issue with the engine's computer system
Symptoms of P1553 Volkswagen
- Decreased fuel efficiency
- Rough idling or stalling
- Hesitation or lack of power during acceleration
- Engine misfires
- Check Engine Light illuminated
How to Fix P1553 Volkswagen
- Perform a diagnostic scan to confirm the P1553 code and identify the specific cause of the pressure ratio issue.
- Inspect the barometric pressure sensor and manifold pressure sensor for any signs of damage or malfunction. Replace if necessary.
- Check for any vacuum leaks in the intake system and repair or replace any damaged hoses or gaskets.
- Replace the air filter if it is clogged or dirty, as this can affect pressure readings.
- Clear the diagnostic trouble codes and test drive the vehicle to ensure that the issue has been resolved.
Cost to Fix P1553 Volkswagen

Frequently Asked Questions about P1553 Volkswagen Code
What does the OBDII code P1553 mean for Volkswagen vehicles?
P1553 indicates a problem with the ratio between the barometric pressure sensor and the manifold absolute pressure (MAP) sensor, suggesting the signals are out of expected range.
What are the symptoms of code P1553 in a Volkswagen?
Symptoms may include poor engine performance, rough idling, stalling, reduced fuel efficiency, and possibly an illuminated check engine light.
What causes the P1553 code in Volkswagen vehicles?
Common causes include a faulty MAP sensor, a defective barometric pressure sensor, wiring or connection issues, or vacuum leaks affecting the intake manifold.
Can a dirty air filter cause the P1553 code?
Yes, a severely clogged air filter can disrupt airflow, potentially affecting pressure readings and contributing to this code.
How can you diagnose the P1553 code in a Volkswagen?
Diagnosis involves scanning for additional codes, inspecting MAP and barometric pressure sensor data, checking wiring and connections, and testing for vacuum leaks.
Can the P1553 code affect engine performance?
Yes, incorrect pressure readings can disrupt fuel-air mixture calculations, leading to poor performance and reduced efficiency.
Is it safe to drive with the P1553 code present?
While the vehicle may still run, driving with this code can lead to further engine damage or reduced fuel economy, so repairs should be prioritized.
How do you fix the P1553 code in a Volkswagen?
Repairs may involve replacing the faulty MAP or barometric pressure sensor, repairing damaged wiring, cleaning the throttle body, or addressing vacuum leaks.
What tools are needed to troubleshoot the P1553 code?
An OBDII scanner, multimeter, and possibly a vacuum gauge are essential tools for diagnosing this issue.
Can clearing the code resolve the P1553 issue?
Clearing the code without addressing the underlying issue may temporarily hide the problem, but the code is likely to return.
