What is a P0115 code mean?
P0115 is the OBD-II generic code that indicates when the engine control module (ECM) reads the ECT sensor input go below or above the sensors expected range of 0.14 to 4.91 V (-40°C to 140°C -40°F to 284°F).
How is DTC P0115 diagnosed?
What are the Common Symptoms of the P0115 Code?
- Malfunction indicator lamp (MIL) or check engine light illuminated.
- Engine may be hard starting.
- Poor fuel economy.
- Engine running extremely rich or lean.
- Engine dying.
- Engine overheating.
- In many cases, no unusual symptoms may be noticed.
What does engine coolant temperature low circuit mean?
Diagnostic trouble code (DTC) P0117 stands for “Engine Coolant Temperature Sensor 1 Circuit Low.” It indicates that the vehicle’s powertrain control module or PCM has detected a low voltage input from the engine coolant temperature (ECT) sensor 1.
What trouble code would the PCM set for a bad ECT sensor?
The ECT sensor resistance will appear high when the coolant temperature is low and vice versa. If the PCM detects that the signal voltage is lower than the normal operating range of the sensor, then it triggers the error code P0117.
What is code p1509?
The code P1509 is a problem with the idle air control valve or circuit. The most common failure is an idle air control valve internal short.
What is OBD II code p011b?
Anecdotally this code seems more common on Toyota vehicles (Tundra, Tacoma, Corolla, etc.). When a code P011B is stored in an OBD-II vehicle, it means that the powertrain control module (PCM) has detected a problem with the correlating signals between the engine coolant temperature (ECT) sensor and the intake air temperature (IAT) sensor.
What is a p1135 code?
OBD-II code P1135 represents a general fault in the air/fuel sensor heater circuit for bank 1, sensor 1. The air/fuel ratio sensor needs to reach a certain operating temperature, a minimum of 1200 degrees fahrenheit, to create accurate voltage signals.
What is a code P115?
Code = Manafacturer Control Fuel Air Metering p115 was the fault code. I am thinking that there is either fuel in the avaporator canister or the gas cap is bad (seems unlikely).
