Parts for your 2022 Mazda Cx-5-Throttle position sensors

2022 Mazda CX-5 throttle position sensor (TPS)

Based on technical documentation, the 2022 Mazda CX-5 is fitted with a throttle position sensor. Mazda’s Workshop Manual for the 2022 CX-5 (SKYACTIV‑G 2.5 and 2.5T) describes an electronic throttle body that contains dual Throttle Valve Position sensors (often labelled TP Sensor No.1/No.2) as part of the Electronic Throttle Control system. The OBD‑II diagnostics used by Mazda also reference TPS‑related DTCs (such as P0121–P0123 and P0221–P0223), confirming the sensor’s presence and role.

On this model, the TPS is built into the electronic throttle body and continuously reports the exact angle of the throttle plate to the engine control module. That live feedback helps the ECU balance air and fuel, smooth out idle, sharpen throttle response, and coordinate with systems like the automatic transmission, stability control, and cruise control. With the pedal position sensors at the accelerator and the TPS in the throttle body working together, the CX‑5 delivers predictable, efficient power under all sorts of Aussie and Kiwi driving conditions—from city commutes to long open‑road kilometres.

There’s no routine replacement interval for the TPS on a 2022 CX‑5. It’s a sealed, non‑serviceable component within the throttle body and is only replaced if it fails or falls out of calibration. Signs to watch for include:

• Intermittent hesitation, surging, poor fuel economy, or stalling under light throttle
• High or unstable idle, limp‑home behaviour, or cruise control dropping out
• Check engine light or Mazda’s wrench indicator with codes like P0121–P0123/P0221–P0223

Before condemning the sensor, it’s worth having an auto sparky or technician run live data checks to confirm the TPS signal tracks smoothly with pedal input and that wiring, grounds, and connectors under the bonnet are in good nick. Voltage drop tests and correlation checks (APP vs TP) are standard workshop procedures noted in service literature.

If replacement is required, the fix is typically a complete throttle body assembly rather than a separate sensor swap. Recommended best practice:

1. Use an OEM‑quality throttle body and a new gasket, don’t manually force the throttle plate.
2. Torque fasteners evenly, check for intake leaks, and clear any stored DTCs.
3. Perform throttle/idle relearn with a capable scan tool as specified in Mazda procedures, some vehicles may also need a short drive cycle for final adaptation.

Maintenance‑wise, keep the intake tract clean and ensure the air filter is replaced on schedule. If cleaning the throttle bore for carbon build‑up, use the correct cleaner sparingly and avoid flooding the shaft area to protect the internal sensors.

Does the 2022 Mazda CX‑5 have a throttle position sensor?

Yes. The 2022 CX‑5 uses electronic throttle control, and the throttle body integrates dual throttle position sensors that report throttle plate angle to the ECU. This design is documented in Mazda service materials and supported by the vehicle’s OBD‑II diagnostic trouble codes for TPS circuits.

How often should the TPS be replaced on a 2022 CX‑5?

There’s no scheduled replacement interval. The TPS is sealed within the throttle body and is replaced only if it’s faulty. A proper diagnosis should confirm sensor performance and wiring integrity before any parts are fitted. If required, replacement generally means a complete throttle body plus a relearn procedure.

Can the vehicle be driven with a faulty TPS?

It may run, but it can slip into limp mode, surge, or stall, which isn’t safe. Driving with an erratic TPS can also increase fuel use and stress other components. It’s best to have it scanned promptly and repaired to restore proper throttle behaviour.
