Frequently Asked Questions
What does P0545 mean on a Power Stroke?
P0545 means Exhaust Gas Temperature Sensor Circuit Low (Bank 1 Sensor 1). The exhaust gas temperature sensor signal is below its normal range, which usually points to a short to ground or a failed sensor.
Is P0545 a Power Stroke-specific code?
No. P0545 is a generic OBD-II code defined by SAE J2012, so it means the same thing on any vehicle that sets it. The exact conditions Ford uses to set it on its diesels are in Ford service information.

How Do You Diagnose POWERSTROKE-P0545?
Inspect the exhaust gas temperature sensor connector and harness.
Check the exhaust gas temperature sensor reference voltage, ground and signal against the service specification.
Check for other codes that share the same sensor reference voltage or ground.
