Factory diagnostic troubleshooting wire for fault code P2135 (P2135: Throttle/Pedal Position Sensor/Switch A / B Voltage Correlation) specifically on the Honda CR-V (2020–2026, 1.5L Turbo (190HP) / 2.0L Two-Motor Hybrid (204HP)).
1. Symptoms of P2135 on Honda CR-V
When the Engine Control Module (ECM/PCM) on your Honda CR-V (1.5L Turbo (190HP) / 2.0L Two-Motor Hybrid (204HP)) logs fault code P2135, drivers commonly observe:
2. Most Likely Causes on Honda CR-V
Historical warranty claims and technical repair bulletins for Honda CR-V point to the following failure distribution:
3. Step-by-Step DIY Repair Guide for Honda CR-V
Interface with the diagnostic port or system console using verified scanning hardware. Record freeze-frame data, active sub-codes, and timestamps to isolate whether P2135 is static or intermittent. on the Honda CR-V equipped with 1.5L Turbo (190HP) / 2.0L Two-Motor Hybrid (204HP).
Visually inspect the physical component (Accelerator Pedal Sensor / TPS), connector pins, and associated wiring harnesses for signs of corrosion, thermal melting, or loose grounding clips. on the Honda CR-V equipped with 1.5L Turbo (190HP) / 2.0L Two-Motor Hybrid (204HP).
Measure reference voltages and resistance thresholds against manufacturer factory specifications. Replace any component failing nominal impedance tolerances. on the Honda CR-V equipped with 1.5L Turbo (190HP) / 2.0L Two-Motor Hybrid (204HP).
Install genuine OEM replacement hardware or execute registry / service commands. Ensure all mounting bolts are torqued to factory specifications. on the Honda CR-V equipped with 1.5L Turbo (190HP) / 2.0L Two-Motor Hybrid (204HP).
Erase the fault code from non-volatile memory. Perform a standard verification cycle (e.g. 15-minute mixed drive or system stress benchmark) to ensure monitors reset to 'Ready' state without recurrent fault flags. on the Honda CR-V equipped with 1.5L Turbo (190HP) / 2.0L Two-Motor Hybrid (204HP).

4. Honda CR-V P2135 FAQs
What causes code P2135 to trigger on a Honda CR-V?
On the Honda CR-V (1.5L Turbo (190HP) / 2.0L Two-Motor Hybrid (204HP)), P2135 is most frequently caused by Component aging, oxidation, or degraded internal circuit element (Accelerator Pedal Sensor / TPS) or Wiring harness abrasion, loose terminal pin, or ground voltage float.
Where is the OBD-II port located on my Honda CR-V?
On the Honda CR-V, the 16-pin DLC diagnostic connector is located Driver side lower knee panel. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.
Can I safely drive my Honda CR-V with code P2135?
No. Immediate shutdown / repair required to prevent permanent hardware destruction or total system lockup. Given that P2135 carries a Critical severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
