Code P1573 Mazda Description
The P1573 diagnostic trouble code (DTC) for Mazda vehicles indicates that the throttle position sensor signal is not available. The throttle position sensor (TPS) is a crucial component of the electronic throttle control system, responsible for monitoring the position of the throttle pedal and sending this information to the engine control module (ECM). When the ECM does not receive a signal from the TPS, it can lead to various issues with the vehicle's performance.
Common Causes of P1573 Mazda
- Failed throttle position sensor
- Damaged or corroded wiring/connectors related to the TPS
- Faulty ECM or electronic throttle control module
- Poor electrical connection or voltage supply to the TPS
Symptoms of P1573 Mazda
- Erratic engine behavior, such as surging or hesitation during acceleration
- Rough idling or stalling when coming to a stop
- Reduced engine power or acceleration response
- Illuminated check engine light on the dashboard
How to Fix P1573 Mazda
- Perform a visual inspection of the throttle position sensor and associated wiring for any visible damage or corrosion.
- Use a multimeter to test the TPS for proper voltage readings according to manufacturer specifications.
- Check the continuity of the wiring harness between the TPS and ECM to ensure there are no breaks or shorts.
- If necessary, replace the throttle position sensor or repair/replace any damaged wiring/connectors.
- Clear the DTC from the ECM memory and perform a test drive to verify that the issue has been resolved.
Cost to Fix P1573 Mazda
The typical repair costs for addressing a throttle position sensor signal not available issue can vary depending on the specific cause of the problem and the labor rates at the auto repair shop. In general, replacing a faulty throttle position sensor can cost between $100 and $300, while addressing wiring or ECM issues may increase the overall repair cost. Including parts and labor, the total repair bill could range from $150 to $500 or more. It's advisable to consult with a trusted mechanic or repair shop for an accurate estimate based on the specific circumstances of your Mazda vehicle. Please note that labor rates can fluctuate based on location, vehicle make and model, and the complexity of the repair.

Frequently Asked Questions about P1573 Mazda Code
1. What does the OBDII code P1573 mean on a Mazda?
P1573 indicates that the Throttle Position Sensor (TPS) signal is not available or has been lost, which can affect the vehicle's throttle control system.
2. What are the common symptoms of the P1573 code in a Mazda?
Symptoms may include poor acceleration, reduced engine performance, an illuminated check engine light, and in some cases, the vehicle entering limp mode.
3. What causes the P1573 code to appear in a Mazda?
Common causes include a faulty Throttle Position Sensor, damaged wiring or connectors in the TPS circuit, a malfunctioning throttle body, or a failing engine control module (ECM).
4. Can a dirty throttle body cause the P1573 code?
Yes, a dirty throttle body can disrupt the TPS readings and potentially trigger the P1573 code.
5. How do you diagnose the P1573 code on a Mazda?
Diagnosis involves scanning for additional codes, inspecting the TPS and its wiring for damage, cleaning the throttle body, and testing the sensor with a multimeter.
6. Can you drive a Mazda with the P1573 code?
It’s possible to drive, but it’s not recommended as the vehicle may experience reduced performance or enter limp mode, which could compromise safety.
7. Is replacing the Throttle Position Sensor the only fix for the P1573 code?
No, the issue could also stem from wiring problems, a dirty throttle body, or a failing ECM, so proper diagnosis is essential before replacing parts.
8. How much does it cost to fix the P1573 code in a Mazda?
The cost depends on the root cause. Replacing a TPS typically costs $100–$300, while throttle body cleaning or wiring repairs may be less expensive.
9. Can a software update fix the P1573 code on a Mazda?
In rare cases, a software update for the ECM may resolve the issue if it’s related to electronic communication errors.
10. How can you prevent the P1573 code from occurring again?
Regular maintenance, such as cleaning the throttle body, inspecting wiring, and addressing sensor issues promptly, can help prevent this code from recurring.
