OBD Diagnostic Codes

It's an Emission Control Error Code DTCP0420: Catalytic System Efficiency Below Threshold

NOTE: If some of the DTCs listed below are stored at the same time as DTC P0420, troubleshoot those DTCs first, then recheck for DTC P0420.

P0137, P0138: Secondary HO2S (Sensor 2)

P0141: Secondary HO2S (Sensor 2) Heater USUALLY (but not always) it's an Oxygen Sensor that's bad. If they both check out okay you will probably need to have the catalytic converter replaced.

Trouble code P0118 means: Engine Coolant Temperature Circuit High Input

The diagnostic connector is under the dash on the driver side.

Cylinder 8 misfire detected

Often the front coil pack failing. Burning up the #8 sparkplug is a common indicator.

Trouble code P0335 means: Crankshaft position sensor "A" circuit malfunction

P0300 is multiple or random cylinder misfire.

Trouble code P0202 means: Injector circuit malfunction - cylinder #2

The 1684 code shows a lack of power to the transmission. Check the wiring to the transmission for damage, and worn or improperly connected plugs.

1996 model year and later the obd plug is under the dash on the driver side. 1995 and before it was in different locations depending on make and model.

Trouble code P1296 means: No 5 volts to MAP sensor

Trouble code P1504 means: Idle air control (IAC) circuit malfunction

Your indicator is telling you that you are not in neutral and it will not engage the starter until you are, if the machine is in fact in neutral, or if the clutch is depressed then the sensor that detects it is bad or needs adjustment. the failsafe is the system that keeps you from starting the vehicle in gear.

12 flashes, gear position switch system, probable faulty partgear position switch or related wiring, or ECU

The PCM stores P0700 when it detects a code stored in the tcm. You need to check the transmission computer with a scan tool to know possible causes.

To access trouble codes on a 2002 Cadillac STS without an OBD-II tool, you can use the key-on, engine-off method. Turn the ignition key to the "On" position without starting the engine, then quickly turn it off and back to "On" three times in succession. The dashboard warning lights will flash, and the codes will be displayed in a sequence on the dashboard. Note that this method may not work for all issues and is less reliable than using an OBD-II scanner.

In a 2009 Kia Optima, the OBD II port is located beneath the dashboard, near the driver's side. Specifically, you can find it to the left of the steering wheel, just above the brake pedal. It is usually positioned within easy reach for connecting diagnostic tools.

No, an IFSC code (Indian Financial System Code) and a sort code serve different purposes in banking systems. The IFSC code is used in India to uniquely identify bank branches for electronic fund transfers, particularly within the National Electronic Funds Transfer (NEFT) and Real Time Gross Settlement (RTGS) systems. In contrast, a sort code is used in the UK to identify specific bank branches for processing payments and transfers. While both codes help facilitate transactions, they are specific to their respective countries' banking systems.

The P1258 trouble code typically indicates a problem with the Variable Valve Timing (VVT) system, often related to the VVT sensor or the oil control valve. To fix this code, start by checking the oil level and quality, as low or dirty oil can affect VVT operation. Next, inspect the VVT sensor and oil control valve for any signs of damage or malfunction, and replace them if necessary. Finally, clear the code and perform a test drive to ensure the issue is resolved.

Code B1 on a 2012 Honda Civic indicates that it's time for routine maintenance. Specifically, it usually means the vehicle requires an oil change, engine oil filter replacement, and a general inspection of various components, including the brakes and tires. Additionally, it may involve checking fluid levels and replacing the air filter. It's advisable to consult the owner's manual or a mechanic for specific services associated with this code.
