Code P0221 Mazda Description
The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the Engine Control Module (ECM) In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
What are the Possible Causes of the DTC P0221 Mazda?
- Throttle Position Sensor (TPS) harness is open or shorted
- Throttle Position Sensor (TPS) circuit poor electrical connection
- Faulty Throttle Position Sensor (TPS)
- Fault Electric Throttle Control Actuator (or Throttle Body Motor)
- Accelerator Pedal Position Sensor (APP)

What are the common symptoms of code P0221 in a Mazda?
Symptoms include poor acceleration, erratic idle, engine hesitation, reduced engine power mode (limp mode), and the check engine light turning on.
What causes the P0221 code to appear in a Mazda?
Common causes include a faulty throttle position sensor, damaged or corroded wiring, a malfunctioning accelerator pedal position sensor, or issues with the PCM (Powertrain Control Module).
Can I drive my Mazda with a P0221 code?
Driving with a P0221 code is not recommended, as it may lead to unsafe driving conditions due to reduced engine power or throttle response issues.
How do you diagnose the P0221 code on a Mazda?
Diagnosis typically involves scanning the vehicle with an OBDII scanner, inspecting the throttle and pedal position sensors, checking wiring and connections, and testing the PCM for faults.
What tools are needed to fix a P0221 code on a Mazda?
Common tools include an OBDII scanner, a multimeter for testing electrical circuits, and basic hand tools to remove and replace sensors if necessary.
How much does it cost to repair code P0221 on a Mazda?
Repair costs vary, but replacing a throttle position sensor typically ranges between $100 and $300, including parts and labor.
Can a faulty throttle body cause a P0221 code in a Mazda?
Yes, a malfunctioning throttle body or its internal components can lead to a P0221 code if it affects the throttle sensor readings.
How can I prevent the P0221 code from returning on my Mazda?
Regular maintenance, such as cleaning the throttle body, inspecting sensor connections, and avoiding water or debris exposure to sensitive components, can help prevent recurrence.
Will clearing the P0221 code with an OBDII scanner fix the issue?
Clearing the code may temporarily turn off the check engine light, but the underlying issue must be resolved to prevent the code from returning.
