P1380 GEO Possible Causes
- Repair other codes first
How do I fix code P1380 GEO?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Tech Notes
- If the P1380 code is set with other codes, repair other codes first and then clear the code.
Cost of diagnosing the P1380 GEO code
The cost of diagnosing the P1380 GEO code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected
If the Electronic Brake Control Module (EBCM) detects a condition which will not allow the EBCM to properly identify rough road situations while a misfire condition is being detected by the Powertrain Control Module (PCM), DTC P1380 will set.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1380 GEO Description
The Powertrain Control Module (PCM) receives rough road information from the Electronic Brake Control Module (EBCM) on the serial data circuit. The PCM uses the rough road information in order to enhance the misfire diagnostic by distinguishing crankshaft speed variations caused by driving on rough road surfaces from the variations caused by true misfires. The EBCM transmits rough road information based on the inputs from the wheel speed sensors.
