P0175 on the 2022 Toyota Camry
A P0175 code on your 2022 Toyota Camry indicates bank 2 is running rich — the air-fuel mixture has too much fuel. The 2022 Camry offers the 2.5L Dynamic Force four-cylinder (203 hp) with the D-4S dual injection system, the 3.5L V6 (301 hp) in the XSE and TRD trims, and a 2.5L hybrid. The P0175 code is most relevant to the V6, which has a distinct bank 2 cylinder group. On the 2.5L four-cylinder, bank 2 fuel trims are still monitored by the ECM.
What You'll Notice
- Check engine light on
- Exhaust smells strongly of fuel
- Rough or shaky idle
- Black residue at the tailpipe
- Fuel economy drops below the rated 22–39 mpg range
- Possible misfires at idle or light throttle
Causes Specific to the 2022 Camry
1. O2 Sensor Malfunction (High Likelihood)
The oxygen sensors on the 2022 Camry monitor exhaust gas for fuel trim adjustments. On the V6, the bank 2 upstream sensor is dedicated to the rear cylinder bank. On the 2.5L four-cylinder, the primary sensor controls fuel for all cylinders. A sensor reading falsely lean triggers the ECM to add fuel. At 2-4 years old, premature sensor failure is possible but not common on Toyota's reliable engines. Check sensor response time and voltage patterns with a scan tool.
2. Leaking Fuel Injector (Medium Likelihood)
On the V6, bank 2 port injectors can develop seal issues. On the 2.5L D-4S engine, both port and direct injectors serve each cylinder, and either type can develop sealing problems. Direct injectors are more susceptible due to extreme operating pressures. Inspect spark plugs for fuel fouling to identify the affected cylinder.
3. Fuel Pressure Issue (Medium Likelihood)
The D-4S system on the 2.5L manages dual fuel pressure circuits. The V6 uses a conventional port injection system. In either case, elevated fuel pressure from a faulty regulator or sensor causes excess fuel delivery. Monitor fuel rail pressure at idle and under load with a Toyota-compatible scan tool.
4. MAF Sensor or Intake Issue (Low Likelihood)
A MAF sensor overreading causes the ECM to inject too much fuel. On the V6, this would typically trigger both P0172 and P0175. On the 2.5L, a MAF issue affects the entire engine uniformly. Clean the MAF sensor as a low-cost first step.
Diagnostic Steps
- Identify your engine — 2.5L four-cylinder, V6, or hybrid — as diagnostics differ.
- Read all codes — Check for P0172 (bank 1 rich) alongside P0175.
- Monitor fuel trims — LTFT below -10% confirms active rich correction.
- Test O2 sensors — Compare performance between banks on the V6.
- Check fuel pressure — Verify regulator and rail pressure specifications.
Repair Costs
- O2 sensor: $100–$260
- Fuel injector: $120–$350
- Fuel pressure regulator/sensor: $140–$320
- MAF sensor: $80–$210
Warranty Check
The 2022 Camry should still be within Toyota's 3-year/36,000-mile basic warranty. The powertrain warranty extends to 5 years/60,000 miles. O2 sensors are covered for 8 years/80,000 miles under federal emissions warranty. Contact your Toyota dealer to verify coverage.
Toyota Reliability Context
Toyota engines, including the 2.5L Dynamic Force and the 3.5L V6, are known for exceptional reliability. A P0175 code doesn't indicate a fundamental problem — it's typically a single component issue that's easily resolved. Once repaired, your Camry should return to its usual dependable operation.
