Code P0222 Acura Description

The electronic throttle control system controls the throttle valve opening. The system includes the throttle actuator, the throttle valve, Throttle Position (TP) sensors 'A' and 'B', the Electronic Throttle Control System (ETCS) control relay, the Accelerator Pedal Position (APP) sensor, and the Powertrain Control Module (PCM). TP Sensor 'B' is a semiconductor type, and it is attached to the throttle body and shaft to determine the throttle valve position. The throttle valve position signal from TP Sensor 'B' is transmitted to the PCM for target position feedback control. If the signal from TP Sensor 'B' is a fixed value for a set time, the PCM detects a TP Sensor 'B' malfunction and stores a Diagnostic Trouble Code (DTC).

P0222 indicates that the Throttle Position Sensor (TPS) 'B' circuit is reporting a voltage level lower than the expected range to the engine control module (ECM).

2. What are the common symptoms of code P0222 on an Acura?

Symptoms may include poor acceleration, engine stalling, rough idling, reduced fuel efficiency, and the check engine light being illuminated.

3. What causes P0222 to trigger on an Acura?

Common causes include a faulty throttle position sensor, damaged or corroded wiring, a loose or defective connector, or a malfunctioning ECM.

4. Can I drive my Acura with a P0222 code?

Driving with a P0222 code is not recommended as it may cause unpredictable throttle response and potential safety issues.

5. How do I diagnose a P0222 code on my Acura?

Start by inspecting the TPS wiring and connectors for damage or corrosion, test the voltage output of the TPS, and check for continuity in the circuit.

6. How do I fix the P0222 code on an Acura?

Repairs may involve replacing the throttle position sensor, fixing damaged wires or connectors, or reprogramming or replacing the ECM if necessary.

7. How much does it cost to repair a P0222 code on an Acura?

The cost can vary. Replacing a TPS typically ranges from $150 to $300, including parts and labor, but wiring or ECM repairs may increase costs.

9. What tools are needed to troubleshoot a P0222 code on an Acura?

You’ll need an OBDII scanner, a multimeter, and possibly a wiring diagram for your Acura’s TPS circuit.

10. Does the P0222 code mean the throttle position sensor must be replaced?

Not always. While the TPS is a common culprit, the issue could also stem from wiring, connectors, or the ECM, so proper diagnosis is essential.
