What is OBD-II Code P2355 – Cylinder 10 Pressure Sensor Circuit High?
OBD-II stands for On-Board Diagnostics, a standardized computer system in vehicles that monitors and detects any malfunctioning components within a vehicle’s engine and transmission system. If a problem is detected, the OBD system reports a diagnostic trouble code (DTC). OBD-II Code P2355 is one of these diagnostic trouble codes that indicate a problem with the Cylinder 10 Pressure Sensor Circuit High in a vehicle.
The Cylinder 10 Pressure Sensor Circuit High DTC code triggers when there is an excessive voltage input detected in the Cylinder 10 Pressure Sensor circuit. The Cylinder 10 Pressure Sensor Circuit is responsible for measuring the pressure readings in Cylinder 10 of the engine, which helps the engine control module (ECM) to optimize engine performance.
The normal voltage range for Cylinder 10 Pressure Sensor Circuit ranges from 0.10 volts to 4.5 volts. If the voltage reading exceeds 4.5 volts, it will trigger the Cylinder 10 Pressure Sensor Circuit High DTC code. The ECM may detect such high voltage readings even when the engine is not running, potentially indicating an electrical problem within the circuit.
What Causes OBD-II Code P2355 – Cylinder 10 Pressure Sensor Circuit High?
Different factors can trigger OBD-II Code P2355 – Cylinder 10 Pressure Sensor Circuit High DTC code, including:
1. Loose or damaged wiring – damaged wiring, connectors, or electrical components in the Cylinder 10 Pressure Sensor Circuit can trigger the Code P2355. Any damages caused by corrosion, moisture, or dirt can affect the Circuit’s performance.
2. Malfunctioning Cylinder 10 Pressure Sensor – The Cylinder 10 Pressure Sensor can malfunction if it becomes faulty or damaged. The sensor may develop physical damages, such as cracks, pressure leaks, or wire damages that can affect the electrical signals it generates.
3. Failing ECM: A malfunctioning or failed Engine Control Module (ECM) can also trigger Code P2355. The ECM controls the pressure sensor detection and regulation circuit, and a failing ECM can affect the circuit’s functioning.
What Are the Symptoms of OBD-II Code P2355 – Cylinder 10 Pressure Sensor Circuit High?
Whenever OBD-II Code P2355 is triggered, the vehicle’s performance can become severely impacted, presenting the following symptoms:
1. Illuminated Check Engine Light – Code P2355 will trigger the check engine light, indicating that there is an issue within the Cylinder 10 Pressure Sensor Circuit.
2. Engine Misfire – When the pressure sensor circuit in Cylinder 10 sends incorrect or fluctuating signals to the ECM, the engine can misfire or run erratically, affecting the vehicle’s overall performance.
3. Reduced Engine Power – The engine may lose power and become sluggish when the Cylinder 10 Pressure Sensor supply pressure readings are incorrect.
4. Drop in Fuel Efficiency – When Code P2355 is triggered, the engine may start consuming more fuel than usual, reducing fuel economy.
How to Diagnose OBD-II Code P2355 – Cylinder 10 Pressure Sensor Circuit High?
To diagnose the root cause of OBD-II Code P2355, technicians follow a set of standard practices that include:
1. Scanning the Vehicle’s ECM- When the Code P2355 is triggered, the Check Engine Light will illuminate. Technicians will connect a scan tool to read the diagnostic trouble codes stored in the ECM.
2. Visual Inspection of the Circuit- A visual inspection of the Cylinder 10 pressure sensor circuit may uncover any damages such as corrosion in the wiring connections, visual deformities on the cylinder pressure sensor, or loose connections.
3. Check Cylinder 10 Pressure Sensor Circuit Voltage- Technicians will measure the voltage reading in the circuit of Cylinder 10 Pressure Sensor using a digital multimeter/caliper. If the Voltage reading exceeds 4.5 volts, it confirms the presence of OBD-II Code P2355.
4. Cylinder 10 Pressure Sensor Function Tests: Technicians may conduct functional tests on the Cylinder 10 Pressure Sensor using specialized equipment known as vacuum/pressure gauges or scope meters. The test results can indicate whether the Cylinder 10 Pressure Sensor is operating correctly or requires replacement.
How to Repair OBD-II Code P2355 – Cylinder 10 Pressure Sensor Circuit High?
Once the diagnosis reveals the root cause of the cylinder 10 Pressure Circuit High error, technicians can follow these steps to repair the code P2355:
1. Repairing Loose or Damaged Wiring- If the visual inspection reveals loose or damaged wiring or connectors, the technicians can repair or replace the damaged parts.
2. Cylinder 10 Pressure Sensor Replacement – If the functional tests indicate that the Cylinder 10 Pressure Sensor needs replacement, technicians will remove the faulty sensor and replace it with a new one.
3. Replacing the ECM- If the diagnosis points to the ECM as the cause of Code P2355, the ECM should be replaced with a new one or reprogrammed to ensure proper functioning.
4. Clearing the Error Code- After repairing or replacing defective components, the technicians must erase the Code P2355 from the ECM using a scan tool.
FAQs About OBD-II Code P2355 – Cylinder 10 Pressure Sensor Circuit High
Q1. What is the Cylinder 10 Pressure Sensor’s function in the engine system, and why is it essential?
Ans. The Cylinder 10 pressure sensor is responsible for measuring and monitoring the pressure readings in Cylinder 10. The sensor sends the information to the Engine Control Module (ECM), which then adjusts the engine’s compression, ignition timing, and fuel injection to optimize the engine’s performance. This makes the Cylinder 10 pressure sensor critical for the engine’s efficient operation and fuel economy.
Q2. What is the voltage range for a typical Cylinder 10 Pressure Sensor Circuit?
Ans. The normal voltage range for a Cylinder 10 Pressure Sensor Circuit ranges from 0.10 volts to 4.5 volts. If the voltage reading exceeds 4.5 volts, it will trigger the Cylinder 10 Pressure Sensor Circuit High DTC code.
Q3. What are the symptoms of a malfunctioning Cylinder 10 Pressure Sensor?
Ans. The symptoms of a malfunctioning Cylinder 10 Pressure Sensor include engine misfires, illuminated check engine light, decreased engine power, and reduced fuel efficiency.
Q4. Can OBD-II Code P2355 trigger an engine misfire?
Ans. Yes, OBD-II Code P2355 can trigger engine misfires. This is because the Cylinder 10 pressure sensor sends incorrect signals to the ECM, leading to an erratic engine performance.
Q5. Can I continue driving the vehicle when Code P2355 triggers?
Ans. Driving with Code P2355 can pose a risk to your vehicle’s engine. The best practice is to stop driving immediately after the code triggers and have the vehicle repaired as soon as possible.
