How to diagnose a check engine code p0117?
How To Diagnose Code P0117 1 Check to see if there are any other codes along with P0117 and clear your Check Engine Light with FIXD. 2 Disconnect the ECT sensor and check the circuit wiring for fraying or a poor connection. 3 Check the cooling system for air pockets or dirty/rusty coolant.
What does the error code p0017 stand for?
The error code P0017 specifically refers to Bank 1 Sensor B. This information helps you understand the exact part that is not working properly. Many engines have multiple banks, each containing some of the cylinders. To know what Bank 1 Sensor B means for your vehicle, you will need to consult a diagram of your engine.
Is the p0016 Cam at XYZ or ABC?
For this type of code, IMHO, not worth it because VCDS, or rather the ECM, can not pin point the cause of the P0016 DTC. From the ECMs point of view, the crank is at [XYZ] location, thus the cam should be at [ABC] location, but it is not… the correlation between the two are out of factory design.
What is the p00xx code for the camshaft?
The ECM/PCM detects any out-of-time situation regarding the crankshaft and camshaft (greater than 9 degrees on a GM) and sets the P00xx codes listed above. Technicians will use an oscilloscope to examine the crank and cam sensor pattern the ECM/PCM is reading while the engine is running.

What does trouble code p0011 mean on a car?
The camshaft (s) is (are) adjusted by the ECM through the use of an oil control valve (s) (OCV) also called variable valve timing control solenoid valves. When trouble code P0011 is set, it means that the intake camshaft in Bank 1 is more advanced than the ECM has told it to be.
What are the symptoms of a p0017 engine malfunction?
Symptoms of a P0017 will or may include: Malfunction Indicator Lamp (MIL) illumination. The engine may run but with reduced performance. The engine may crank but not start. The engine may exhibit a rattle near the harmonic balancer indicating the tone ring is damaged. The engine may start and run, but poorly.
How does the coolant sensor work on a Toyota p0117?
One wire is a 5 volt reference from PCM (Powertrain Control Module) and the other is a ground supplied from PCM. As the temperature of the coolant changes, the resistance of the sensor changes.
What causes a p0117 ECT signal low input?
Potential causes of the P0117 code include: 1 Bad ECT sensor 2 Short to ground on ECT signal circuit 3 Faulty or damaged connectors 4 Wiring harness damaged 5 Loose terminals at ECT or PCM 6 POSSIBLY an overheated engine 7 Bad PCM More …
What does the p0117 code do on a car?
The P0117 code will put the engine ECM to go into a failsafe mode. The failsafe mode may cause engine to run rough and hesitate until the engine warms up to operating temperature. Electrical cooling fans may run continuously. What repairs can fix the P0117 code?
One wire is a 5 volt reference from PCM (Powertrain Control Module) and the other is a ground supplied from PCM. As the temperature of the coolant changes, the resistance of the sensor changes.
When does AutoZone send an error code p0171?
The optimal ratio is 14.7:1 (air:fuel). When your powertrain/engine control module receives a reading that indicates there’s too much oxygen and the ratio is incorrect, it sends an error code P0171 or P0174. Depending on the problem, it may send both codes if the issue is causing a lean condition on both engine banks.
Potential causes of the P0117 code include: 1 Bad ECT sensor 2 Short to ground on ECT signal circuit 3 Faulty or damaged connectors 4 Wiring harness damaged 5 Loose terminals at ECT or PCM 6 POSSIBLY an overheated engine 7 Bad PCM More
What happens to your car when you get a p0125 code?
Your vehicle may still operate while getting the P0125 code, but your engine could overheat. It will affect your gas mileage and could even damage your engine if you do not diagnose the problem. If you must pass emissions tests, the P0125 code could prevent you from passing.
What does p0126 and p0128 stand for?
P0126 means “Insufficient Coolant Temperature for Stable Operation,” while P0128 means “Engine Coolant Temperature Below Thermostat Regulating Temperature.” If the P0125 occurs with one of these, you’ll need to look up their causes and symptoms so you can determine the cause of this engine problem more efficiently.
What does the p0117 code on my car mean?
The P0117 code indicates a problem with one of the engine coolant temperature sensors in your vehicle. Find out more about this error code and what to do in case you encounter it using this short guide.

What causes the engine coolant temperature sensor p0117?
There are a lot of issues that could trigger the engine code P0117. Below are just some of the possible causes of P0117: Defective engine coolant temp sensor; Cooling system problems leading to engine overheating; Damaged or corroded engine coolant temp wiring or connection; Air pocket in the coolant System; PCM issues
