Code Definition

P1190 — Calibration Resistor Out Of Range

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

About P1190

P1190 is a manufacturer-specific powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1190 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour.

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.

P1190 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 Engine Control Module (ECM) monitors the calibration resistor circuit to identify the correct engine or system variant and to apply the appropriate control strategies. DTC P1190 is set when the ECM detects a resistance value outside the calibrated acceptable range, indicating an invalid or implausible calibration input. This fault is typically logged when the resistor value is incorrect, the circuit is open or shorted, or the expected calibration reference is missing.
