What Does P1195 Mean?
This code indicates either the EGR pressure sensor (on 1.6L engines) or turbo boost pressure sensor (on 1.8L engines) has an open or short circuit. The specific sensor depends on engine displacement.
Common Causes
40%
Failed EGR or boost pressure sensor with internal fault
30%
Damaged wiring harness or connector to pressure sensor
15%
Corroded or bent connector pins causing open or short
10%
Vacuum line disconnected or leaking (EGR pressure sensor)
5%
ECU internal fault in sensor input circuit
Diagnostic Steps
1
Step 1: Identify which sensor applies to your engine (1.6L=EGR pressure, 1.8L=boost pressure)
2
Step 2: Disconnect sensor connector and measure sensor resistance or voltage output per specifications
3
Step 3: Check for proper reference voltage at sensor connector (typically 5V) with key on
4
Step 4: Inspect wiring harness for damage, particularly near heat sources or moving components
5
Step 5: If applicable, verify vacuum supply to EGR pressure sensor is present and free of leaks
Estimated Repair Cost
$100 - $450
Parts + labor, varies by vehicle and location
This code indicates either the EGR pressure sensor (on 1.6L engines) or turbo boost pressure sensor (on 1.8L engines) has an open or short circuit. The specific sensor depends on engine displacement.
The most common cause of P1195 (EGR Pressure Sensor (1.6L) or Boost Sensor (1.8L) Open or Short) is: Failed EGR or boost pressure sensor with internal fault
Typical repair costs for P1195 range from $100 to $450, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive but may experience reduced performance, increased emissions (EGR), or improper boost control (turbo engines).
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1195 to identify the root cause.
