What is P2135 : Engine Error code Causes Explained
This Guide covers the P2135 engine trouble code, its causes, and its effects on vehicle performance. A throttle position sensor malfunction might cause poor acceleration, stalling, or engine power loss.
How to Identify a DTCs Number
The P2135 Diagnostic Trouble Code (DTC) is related to the Throttle/Pedal Position Sensor/Switch A/B Voltage Correlation.
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
This code typically occurs when the Powertrain Control Module (PCM) detects a mismatch in the voltage signals between Throttle Position Sensor (TPS) A and B. Connect an OBD-II scanner to the vehicle’s DLC (Diagnostic Link Connector) and check for stored DTCs.
Causes of P2135 Code:
- Faulty sensors:
A faulty TPS or accelerator pedal sensor can send incorrect voltage signals to the ECM. - Faulty ECM:
A faulty ECM can trigger the P2135 code. - Wiring issues:
An open/short in the TPS or accelerator pedal sensor circuit can trigger the code. - Cracked wiring harnesses:
Cracks in the wiring harnesses can cause the code to appear.
Risk Level of P2135 Error Code:
The P2135 code is classified as “High Risk Level,” it means the issue is severe and could lead to dangerous driving conditions.
Immediate inspection and repairs are strongly recommended to prevent further damage and ensure vehicle safety.
Common Car Brands Affected by P2135 Code:
The P2135 engine error code is commonly found in the following list.
- Toyota Camry
- Nissan Altima
