What is a sensor circuit malfunction?
Error Code P0335 is described as Crankshaft Position Sensor “A” Circuit Malfunction. This means the vehicle’s ECM (Electronic Control Module) has not yet detected the crankshaft position sensor during the first second of cranking of the engine.
What causes oxygen sensor code?
Deceptive Oxygen Sensor Codes Engine vacuum leaks that create a lean exhaust condition. Mass airflow sensor failure that creates a rich exhaust condition. Manifold air pressure sensor failure that creates a rich exhaust condition. A defective fuel pressure regulator.
What would a bank 1 sensor 2 measure?
It measures raw exhaust fumes’ composition, and the ECU uses this data to adjust the air-fuel mixture. A potential failure of this sensor will impact engine operation and overall performance. The second sensor is installed behind the catalytic converter, and we call it sensor 2 or a downstream sensor.
What can cause cam sensor code?
What are the Possible Causes of the P0340 Code?
- Failing or defective camshaft position sensor.
- Circuit problems (e.g., damaged wiring, loose connections)
- Errors in the powertrain control module (somewhat rare)
- Damaged camshaft position sensor reluctor wheel.
- Problems with internal engine timing components.
What does the code p0036 mean?
P0036 is the code for Heater Oxygen Sensor Control (HO2S) Circuit (Bank 1, Sensor 2) What the P0036 code mean? P0036 means that for the engine to operate properly, the engine exhaust should have a specific air fuel ratio of 14.7 to 1 as determined by the heated oxygen sensors (HO2S), which detects the oxygen content of the exhaust.
What causes engine code p0138?
The P0138 code is set when the Engine Control Module (ECM) detects that the rear O2 sensor signal voltage remains excessively high for an extended period of time. Possible Symptoms Engine Light ON (or Service Engine Soon Warning Light)
What is code p0138 and p0607?
P0138 is for the O2 sensor. Either shorted or open. P0607 is for ECM problem. Most likely the O2 is the main cause of the problem and the code for a bad ECM is thown in just in case raplacing the O2 sensor or checking the wire harness do not fix the problem.
What is code p0161?
OBD-II Code P0161 is defined as a Oxygen Sensor Heater Circuit Malfunction (Bank 2, Sensor 2) The rear Oxygen Sensor is located in the exhaust system behind the catalytic converter(s).
