P1195 – OBD-II DTC

OBD-II DTC P1195 – Calibration Resistor Out Of Range

DTC P1195 meaning

DTC P1195 refers to a diagnostic trouble code indicating that the calibration resistor is out of range. This code is typically associated with the vehicle’s fuel system and is triggered when the Engine Control Module (ECM) detects an abnormal reading from the calibration resistor, which is crucial for proper fuel mixture and engine performance.

DTC P1195 symptoms

Common symptoms associated with DTC P1195 may include:

• Check Engine Light illuminated
• Decreased engine performance
• Increased fuel consumption
• Rough idling or stalling
• Difficulty starting the engine

DTC P1195 causes

Several factors can lead to the triggering of DTC P1195, including:

• Faulty calibration resistor
• Wiring issues or damaged connectors
• Faulty Engine Control Module (ECM)
• Issues with the fuel system, such as a clogged fuel filter
• Vacuum leaks affecting air-fuel mixture

DTC P1195 seriousness

DTC P1195 can be considered serious as it may lead to poor engine performance and increased emissions. If left unaddressed, it can result in further damage to the engine or fuel system components, potentially leading to costly repairs.

How to diagnose DTC P1195

To diagnose DTC P1195, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the P1195 code.
2. Check for any additional trouble codes that may provide more context.
3. Inspect the calibration resistor and its connections for damage or corrosion.
4. Test the calibration resistor with a multimeter to ensure it is within specifications.
5. Examine the wiring and connectors for any signs of wear or damage.
6. Check the fuel system components for clogs or leaks.
7. Perform a visual inspection for vacuum leaks in the intake system.

How to fix DTC P1195 step-by-step instructions

To fix DTC P1195, follow these step-by-step instructions:

1. Clear the DTC using an OBD-II scanner.
2. Replace the faulty calibration resistor if testing indicates it is out of range.
3. Repair or replace any damaged wiring or connectors associated with the calibration resistor.
4. Address any issues found in the fuel system, such as replacing a clogged fuel filter.
5. Fix any vacuum leaks in the intake system.
6. Recheck the system by running the engine and monitoring for the return of the DTC.

How to erase DTC P1195

To erase DTC P1195, follow these steps:

1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Turn on the ignition without starting the engine.
3. Navigate to the option to clear or erase trouble codes on the scanner.
4. Confirm the action to erase the DTC.
5. Disconnect the scanner and start the engine to ensure the code does not return.
