Code Definition

P1195 — Exhaust gas pressure sensor circuit

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Ford

About P1195

P1195 is a manufacturer-specific powertrain diagnostic trouble code recorded for Ford vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1195 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1195 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The exhaust gas pressure sensor measures pressure in the exhaust system and reports it to the Engine Control Module (ECM), which uses the reading to manage exhaust gas recirculation, diesel particulate filter operation, and back pressure related fuelling on diesel applications. The sensor is fed a reference voltage and returns a signal voltage that rises and falls with exhaust pressure. DTC P1195 is set when the ECM sees the exhaust gas pressure sensor signal outside its normal range or not responding correctly, indicating a circuit or sensor fault. Common triggers include a blocked or cracked...
