P0128

The code has to do with the thermostat not performing as specified, or the temperature sensor is not working correctly. You could first replace the thermostat, since it is the most common cause, and see if the code returns. If...

Hello. The variable valve timing and the camshaft position sensor are two separate sensors. The camshaft position sensor is more towards the front of the engine and is a lot easier to replace. The variable valve timing sensor is a...

The code P0406 (https://www.yourmechanic.com/article/p0406-obd-ii-trouble-code-exhaust-gas-recirculation-sensor-a-circuit-high-by-spencer-clayton) is for the electronic gas recirculation valve high circuit input. Meaning the valves sensor is detecting a high voltage input. This can be due to carbon build up on the valve, a bad valve, or a...

The P0128 code (https://www.yourmechanic.com/article/p0033-obd-ii-trouble-code-turbo-charger-or-supercharger-bypass-valve-control-circuit-by-john-nelson) is most likely caused by one of the following three issues: a faulty thermostat, a faulty engine coolant temperature sensor, or a processing error in the ECM. The coolant temperature needs to measured using a temperature...

This code is a sign that the engine did not get to operating temperature in a specified amount of time and the computer turns on the Check Engine Light. The most common problem is that the engine thermostat is partly...

Code P0128 (https://www.yourmechanic.com/article/p0033-obd-ii-trouble-code-turbo-charger-or-supercharger-bypass-valve-control-circuit-by-john-nelson) is engaged specifically when the engine itself does not get to operating temperature in a specified time period. The only things that can cause this problem is an issue with the thermostat (https://www.yourmechanic.com/services/thermostat-replacement), head temp sensor, and...

Hello. The trouble codes listed are for two distinctly different issues. P0011 is the trouble code for an issue with the vehicle's camshaft position for bank a, being over advanced. This is often caused by a faulty camshaft position sensor...

First, a trouble code P0128 (https://www.yourmechanic.com/article/p0033-obd-ii-trouble-code-turbo-charger-or-supercharger-bypass-valve-control-circuit-by-john-nelson) does have to do with coolant, but it is not the level. This code is set when the relationship between the coolant temperature sensor and the intake air temperature sensor don't increase at a...

This is most likely caused by the thermostat partly stuck open. The coolant sensor would need to be tested to make sure it is not bad, though. I would test the thermostat at the housing with a temperature tester, and...

Hello. This code is indicating that your car’s thermostat is not working properly. Your thermostat needs to be replaced and engine lights needs to be reset. Your car will also need to be test driven. Spark plugs are also recommended...
