2014 chevrolet cruze 1.8L, what cause engine to run rough and stall when first start up?
These codes refer to 3 different issues.
P0053 - HO2S Heater resistance Bank 1, sensor 1.
P0054 - HO2S Heater Resistance Bank 1 Sensor 2
P0324 - Knock Sensor (KS) Module Performance.
P0326 - Knock Sensor Circuit Excessive Spark Retard.
P0597 - Thermostat Heater Control Circuit Open.
You need to get a good mechanic to look at this. The HO2S codes refer to both of the 'O2' sensors in the exhaust, (mounted before and after the Catalytic Converter). They monitor the exhaust gas mixture to correct fuel mixture to the engine to control exhaust gas pollution levels. If one is detecting a wrong reading, the fuel/air mix is automatically adjust.
The Knock sensors detect vibration from when the fuel is burning. If the sensor detects a 'bang' when it shouldn't be there it alerts the ECM (cars brain) to adjust the timing sequence.
Wrong readings cause the ECU to adjust the fuel/air mixture to the wrong setting causing rough engine running.
The thermostat code is for the wiring to the coolant thermostat sensor.
