Code 53 is triggered when there is a fault in the logic module. When code 53 is triggered the power limited will not be lit and the system will not enter limp mode.
Before replacing the logic module, read the page ‘How to troubleshoot drivability issues’. Check the wiring and connections from the logic module to the power module. Clean and re-grease the connectors with dielectric grease. Check the wiring from the O2 sensor to the harness. If the signal wire is grounded it will cause code 53. If that all fails, you may need to replace the logic module.
