P0122 on Your 2024 Honda CR-V: Critical Circuit Fault
A P0122 on your 2024 Honda CR-V is a serious throttle system alert. The ECM has detected that the throttle position sensor voltage has dropped below the minimum threshold—this isn't a calibration or performance issue, it's a circuit failure. The TPS signal has essentially gone dead or critically low.
The 2024 CR-V (6th generation) uses a 1.5L VTEC turbo (190 hp) or a 2.0L hybrid powertrain. Both feature Honda's electronic throttle control with integrated TPS. On a vehicle this new, a manufacturing defect or assembly issue is the primary suspect.
Symptoms
- Check engine light on
- Severe or complete throttle failure
- Engine idles but won't accelerate
- Harsh limp mode
- Possible stalling
Causes on a New CR-V
- Throttle body manufacturing defect – Factory fault in the internal TPS sensor. Likelihood: 35%
- Connector seating issue – Assembly line connector not fully seated. Likelihood: 30%
- Wiring routing damage – Wire pinched or chafed during factory assembly. Likelihood: 20%
- ECM reference voltage fault – 5V supply issue. Likelihood: 10%
- Water intrusion – Moisture in connector from road conditions. Likelihood: 5%
Cost
- All repairs: $0 under warranty
- Out-of-warranty reference: Connector repair $50–$150, throttle body $300–$500, wiring $150–$350
