2005 Taurus Program Codes PO 300 and PO 316

A friend just checked my prgramming because the " see dealer light " came on. He ran a diagnostic and the codes PO 300 and PO 316 were the result. What do these codes indicate??????

Thanks Code PO316 Possible crankshaft position sensor
Codes PO301 and PO308 {# 1&8 cyl mis} PO 171& PO175 Bank 1 too lean ...Bank 2 too rich Could all this be related to a faulty PCM? or maybe the need for 2 new coils and a new CPS sensor? Also, if these parts are changed, will I have to reprogram the computer? Thanks for any advice, I can't afford to bring it in to the dealer {recsntly laid off} Thanks again!

May need to clean the egr valves because if one is stuck then the other bank would be enriched to make up the difference .In order to reset the computer when your done is unhook battery and then reconnect. But realize some radios are subject to needing a code to make them work again because of a theft sensor. Here are some a few sensors and what happens when the don't work right.

ECT sensor
symptoms
Potential Symptoms

Symptoms of a P0118 could include:

* Very poor fuel economy
* A no start condition
* Vehicle may start, but run very poorly, blowing black smoke, running very rough and misfiring
* Illumination of MIL

TPS sensor

Symptoms of a P0121 trouble code could include:

* Malfunction Indicator Lamp
(MIL) illumination (Check Engine Light or Service Engine Soon light)
* Intermittent stumble on acceleration or deceleration
* Blows black smoke on acceleration
* No start

EGR valve

Usually a fault in the control circuit, will leave no noticeable symptoms other than the Malfunction Indicator Lamp (MIL) illumination. However, if the EGR control solenoid
is stuck open due to debris, etc. the code may be accompanied by misfire under acceleration, rough idle, or engine dying altogether.

po171

You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration.
Causes

A code P0171 may mean that one or more of the following has happened:

* The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
* There could be a vacuum leak downstream of the MAF sensor.


These are the main ones
God Bless Greg

Having codes P0306 and P0316 show up for 2005 Ford Taurus


Well code 306 is for a miss on cylinder six and code 316 is for a miss detected on startup, which you probably already know.
Since I assume you have replaced the ignition parts for that cylinder,
the next component to check is the injector. You may want to check fuel pressure too.

Engine Code PO 300 and PO 316 came up when running diagnostic


P0300 is random multiple cylinder misfire and P0316 is misfires detected on start up. This is an ignition related issue. I would check the ignition system and tune up condition and proceed from there also if you have access to a sanner with live data capability check that you have and RPM reading when cranking the engine and the times it deosnt want to start this would indicate an issue with the crank sensor

The engine shape light stays on on dashboard of toyota yaris 2005 what does this mean


This might be a form of the 'service engine soon' or 'check engine' light. Check the codes on the 2005 model year vehicle with an obd-II compliant scanner.

05 corolla, after gassing up, whether partial or full fillup, car is hard to start. will crank but runs rough before going dead. after 3-4 starts and runs fine. toyota dealer checked codes; po 171 system...


Sounds like you may have an issue with the check valve on your in tank fuel pump. When these go bad, you have to crank several time to build up enough pressure in the fuel rail for engine start. With a good check valve, the fuel pressure will not bleed off and the pressure is retained for the next engine start.
