A P0108 says that the ECU is seeing a higher voltage from the Manifold Absolute Pressure (MAP) sensor than it expects. This could be a bad vacuum line, a bad sensor, or a bad electrical connection to the sensor. A...

Hi - the description for each Check Engine problem code contains the clues (https://www.yourmechanic.com/question/o2-sensor-by-andrew-t_3) : for a given code - P1647 for example - the description is "Bank 2, Sensor 1". This means the first sensor in the exhaust system...

Diagnostic trouble code P2004 (https://www.yourmechanic.com/article/p2004-obd-ii-trouble-code-intake-manifold-runner-control-stuck-open-bank-1-by-jamahl-walker) signifies a problem with a segment of the engine's air intake and control system, technically known as the intake manifold runner control (IMRC). In practical terms, the code means that the engine is not getting...

P1081 can appear when there is an issue with the immobilizer or the systems it communicates with. If the immobilizer has been replaced, then it may need to be reprogrammed or matched with the key so that they can communicate...

If the timing chain is badly worn (https://www.yourmechanic.com/services/timing-chain-replacement) very badly, it may cause the engine to run poorly or not start at all. A badly worn timing chain usually comes with noises and a check engine light. Consider having another...

Hey there. I can definitely relate to your frustration. However, one test that might significantly reduce the search for why the check engine light is flashing is to complete a digital scan using a scan tool (https://www.yourmechanic.com/article/what-s-the-difference-between-a-code-reader-and-a-code-scanner). Different from a...

Hello. The ETC code can come on for many reasons, but essentially the engine idle speed control is often times the problem. The fact that it indicated the spark plugs needed to be changed suggests there was a misfire of...

OBD-II came out in late 1995 in some vehicles, and all vehicles from 1996 onwards. You may need to try an OBD-1 scan tool or try to obtain the codes another way. It is also possible that you have some...

Hello. It sounds like your 2002 Porsche Boxster lost all battery power. This occurs when the alternator fails (https://www.yourmechanic.com/services/alternator-replacement) and causes the battery to die. It is a common issue. The battery (https://www.yourmechanic.com/services/battery-replacement) must first be checked and then replaced...

It sounds to me like the dealership simply tightened the gas cap and didn't charge you for it nor recorded the transaction. Not to worry though. I don't believe tightening the gas cap would be the proper repair. What you...

The P0155 (https://www.yourmechanic.com/article/p0155-obd-ii-trouble-code-02-sensor-heater-circuit-malfunction-bank-2-sensor-1-by-jamahl-walker) is the oxygen sensor located on the rear bank of cylinders and before the catalytic converter. Given your mileage, both oxygen sensors (https://www.yourmechanic.com/services/oxygen-sensor-replacement) (pre-catalytic converter) should be replaced. The pre-cat sensors have the most affect on fuel...

Unfortunately, no trouble code (https://www.yourmechanic.com/article/how-to-read-and-understand-check-engine-light-codes-by-jason-unrau) was mentioned with this question. Catalytic converter failure will usually cause trouble codes that are related to the oxygen sensors due to the fact that the oxygen sensors pick up their data based on the...

Hello there, thank you for asking about your 2001 Saab 9-3. These codes can come up if the engine needs a tune up, if it has bad coils, or even if you have dirty fuel injectors. Due to the age...

Each of these codes are for different problems, and would need to be diagnosed. If you are low on coolant, then your misfire may be due to a blown head gasket and the first three codes. The last code, P0768...

You should be able to check the vehicle owners manual for the location of the fuse (https://www.yourmechanic.com/article/how-to-check-fuses-by-rocco-lovetere) that will power the diagnostic port. The fuse is not always the same as the accessory or cigarette lighter socket. If you would...
