P2135 Quick Answer
P2135 on a 2014 Toyota Camry indicates Throttle / Pedal Position Sensor / Switch "A" / "B" Voltage Correlation. Start with a freeze-frame check and a careful inspection of the connector and wiring at the affected device before replacing any parts.
What Does P2135 Mean on a Toyota Camry?
On the 2014 Toyota Camry, the SFI System sets P2135 when it detects a fault matching its official definition: Throttle / Pedal Position Sensor / Switch "A" / "B" Voltage Correlation. This is a manufacturer-specific definition from Toyota factory diagnostic data and applies to the XV50-generation Camry.
Symptoms
- Warning light for the affected system (check engine, ABS, airbag, or a system indicator depending on the module)
- Reduced or lost function of the sfi system
- Possible related codes from other modules on the Camry CAN/LIN network
Common Causes
- Fault in the component named in the definition (throttle / pedal position sensor / switch "a" / "b" voltage correlation)
- Open, shorted, or high-resistance wiring in the affected circuit
- Connector corrosion, water ingress, or a backed-out terminal
- Loss of supply voltage or a poor ground at the device
- Module internal fault — confirm wiring and supplies before condemning the module
Diagnostic Approach
For P2135 on the 2014 Toyota Camry you’ll want an OBD-II scan tool with live-data and freeze-frame support (a Toyota Techstream-class tool reads enhanced data), plus a digital multimeter and the wiring diagram.
- Confirm the code is current, not stored history, and record freeze-frame data.
- Read all modules — related codes often pinpoint the root cause faster than the headline code.
- Inspect and wiggle-test the connector at the named device while watching live data.
- Measure supply voltage and ground integrity at the device; verify the circuit against the Camry wiring diagram.
- Substitute or isolate the suspect device only after wiring and supplies check out.
- Clear the code and road-test through one or two drive cycles to confirm the repair.
Possible Fixes
- Repair open/short/high-resistance wiring or a corroded connector
- Restore supply voltage or ground at the affected device
- Replace the failed component named in the definition
- Replace and, where required, initialise/program the module if it is internally faulty
Can I Still Drive With P2135?
It depends on the system. SFI System faults that affect braking, the airbag/restraint system, power steering, or stability control should be repaired before further driving. Comfort or convenience faults can usually be deferred briefly, but related codes can mask one another on the Camry network — diagnose promptly.
FAQ
Is P2135 specific to the Toyota Camry?
The definition here is taken from 2014 Toyota Camry (XV50) factory diagnostic data. The same code may appear on other Toyota models, but the affected module and exact criteria can differ between platforms.
Can I clear P2135 without fixing it?
You can clear it, but if the underlying fault is still present the Camry will reset the code on the next drive cycle that runs the relevant monitor. Diagnose the cause first.
Will a generic OBD-II reader show P2135?
Most generic readers show powertrain (P) codes, but Toyota-enhanced data (e.g. a Techstream-class tool) gives the full freeze-frame and live data needed to diagnose it properly.
