What is P2088 : Engine Error code Causes Explained
This tutorial covers the P2088 engine error code, its causes, and solutions. Taking care of this exhaust temperature sensor code keeps your car running smoothly and safely.
How to Identify a DTCs Number
The P2088 engine error code corresponds to a malfunction in the exhaust temperature sensor circuit, specifically when the signal from the exhaust gas temperature (EGT) sensor is too high.
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.
To identify the DTC (Diagnostic Trouble Code) number, you can use an OBD-II scanner. Simply plug the scanner into the vehicle’s OBD-II port, which is typically located under the dashboard near the driver’s seat. Once connected, the scanner will display the error codes, including P2088, if that specific issue is present.
Causes of P2088 Error Code:
- Low Engine Oil or Dirty Oil:
Insufficient or contaminated oil can affect the VVT system’s performance. - Wiring Issues:
Damaged or corroded wires/connectors cause low voltage in the camshaft actuator circuit. - Faulty Camshaft Position Actuator.
A malfunctioning actuator can disrupt timing adjustments. - EM/PCM Issues:
A rare but possible cause; a failing ECM may misinterpret sensor data. - Timing Chain/Belt Issues:
A stretched or misaligned timing chain/belt can lead to ir.correct camshatt timing.
Risk Level of P2088 Error Code:
When this error code appears with a high-risk level, it indicates a potentially serious issue with the engine’s emissions system.
While the vehicle remains drivable, ignoring this issue can lead to reduced fuel efficiency and poor engine performance.
Common Car Brands Affected by P2088 Code:
The P2088 engine error code is commonly found in the following list.
- Ford
- Chevrolet
- Kia

FAQ’s
What is P2088 Engine Error Code?
The P2088 error code indicates a malfunction in the exhaust temperature sensor circuit, typically found in the post-turbo or after-treatment system. It signals an abnormal voltage reading from the sensor, affecting emissions control.
What Causes the P2088 Error Code?
P2088 is often caused by a faulty exhaust temperature sensor, wiring issues, or problems in the sensor’s connection. It can also be triggered by excessive exhaust temperatures or issues with the vehicle’s after-treatment system.
What is the Risk Level of the P2088 Code?
The P2088 code is of medium to high risk, as it can impact the engine’s emissions system. If ignored, it can result in improper after-treatment system functioning, reduced fuel efficiency, and potentially increased exhaust emissions.
Which Vehicles are Affected by the P2088 Code?
The P2088 error code typically affects diesel-powered vehicles with a post-turbo exhaust temperature sensor, including models from manufacturers like Ford, Chevrolet and Kia.
