SOURCE: Temp Sensor

The temp sensor known as the engine coolant temp. sensor tells the computer if the engine is overheating and so forth and tells the injectors how much fuel to give the engine. The temp. sending unit is what controls what your guage reads. It sounds like you need the temp. sending unit. It located near the thermostat housing with a single pole connector.

I know this post is old, but right on the engine theres a sticker that says use multi-ground plugs only. I read a similar problem like yours and it seemed to turn out that the spark was arcing to ground over the ceramic on the plug. So maybe it could have something to do with the single ground plugs.

Have you checked for spark on all 8 plugs? Unplug the exhaust side coil pack and run the engine. Does it run on all 4 cylinders?

SOURCE: code came back as iat sensor reading high

IAT stands for Air Intake Temperature Sensor and it is located in the intake tube coming from the air filter box tot he engine. Easiest way to find it is look at the top of your engine where it says 2200. Coming right out of that manifold is a black ribbed tube about the size of a baseball to softball. It should be going towards the direction on the front drivers side. on the back side of that tube, about 4 inches away from the intake manifold (the things that says 2200) is a plug with wires. That is your IAT Sensor. If it is unplugged, plug it back in. Otherwise unplug it and replace it. Make sure to disconnect the battery while you do this so the computer resets itself after the new one is installed. Thanks and please don't forget to rate!

SOURCE: where is Bank 1 sensor 1 located

Start at the exhaust manifold flange on the drivers side. The first sensor you come to before the cat. converter is the sensor you are looking for.

V10 cranks but will not start. If I use starting fluid it will start and stay running. Any ideas?


The coolant temperature sensor is failing. Usually the engine will be slow to start the first time. Turn it off and it will start normally. sometimes will not start cold. There are two sensors one for the gauge and one to the computer that meters fuel to the injectors. This one is located near the thermostat housing has a two wire connector (19MM deep well socket to remove)

Would the coolint temp saners make my jimmy hard to start


scan test for codes first. check data reading with scan tool.If coolant temp sensor reads -40 deg. yes it would be hard to start.

2003 grand marquis with misfire code p0316


The first problem you have is assuming that the ignition coil is the only thing that can cause a misfire.

Diagnostic Test Code (DTC) P0316 is a "continuous memory only" code that indicates that there is a fault causing a misfire during the first 1000 revolutions of the crankshaft immediately after engine start-up. This should be accompanied by the regular cylinder misfire monitors (Codes P0301 through P0310) unless the misfire does not continue long enough for the regular misfire monitors to determine which cylinder is misfiring.

In order to determine what is actually causing the problem, you must have access to a scan tool that can perform Key On Engine Off (KOEO) fault testing and Key On Engine Running (KOER) fault testing as well as interfacing with the onboard engine computer to read live data and perform system tests.

Please note that generic OBD code readers DO NOT have the capabilities to do what you need to diagnose this problem. You will most likely get additional DTCs that can help lead you to find the source of the problem when KOEO and KOER tests are run. Generic OBD code readers can access only continuous memory DTCs.

Possibilities/conditions/systems that can cause this code are:
>Camshaft Position Sensor
>Low fuel: less than 1/8 tank
>Stuck open EGR Valve
>Blocked EGR passages
>Ignition system
>Fuel Injectors
>Fuel injector control circuits
>Running out of fuel
>EVAP canister purge valve
>Fuel Pressure
>Evaporative emissions system
>Base engine (mechanical) problems

Car willnot stay running without one foot on the gas and the other on the brake


The first step with a problem like this is to have the electronic engine control system tested for fault codes, you may have a defective idle speed control system, if this is the case you will also need a "Engine Running" fault code scan as well as a passive memory scan. The 2 tests are referred to as the the Key on engine running test (KOER) and the Key on engine off test (KOEO)

Ford f350 crew cab super duty 7.3 diesel runs rough and turns off randomly while driving sometimes restarts in neutral allot of times i have to stop and put it in park turn key completely off position I...


This is a case of which came first.
The stalling is most likely caused by your Cam Sensor. The description for Diagnostic Test Code (DTC) P0340 is "cam sensor circuit malfunction" This is a VERY COMMON problem on 7.3L diesel engines. Ford has had a lot of trouble with these.

The description for DTC P0470 is "exhaust back-pressure sensor circuit malfunction" This code can be caused by the EBP sensor, the circuits to the EBP sensor or a faulty Powertrain Control Module (PCM)

The description of DTC P1211 is "Injection Control Pressure (ICP) above or below desired" This can be caused by the engine stalling. It can also be caused by several other things, including low engine oil level or a possible faulty PCM. (Check you engine oil level FIRST.)

The troubleshooting charts needed to properly diagnose DTCs P0470 and P1211 depend on whether these codes are Key-On-Engine-Off (KOEO), Key-On-Engine-Running (KOER), or "continuous memory" codes. If you retrieved these codes with a generic OBD scan tool, then they are definately present in "continuous memory". However, a scan tool with the capabilities to read KOEO and KOER codes MUST be used to determine if these are "HARD" or "INTERMIITTENT" faults. The troubleshooting steps vary greatly depending on this information.

Personally, I would start with the lowest number code first (P0340). Replace the cam sensor. Please note: this is the MOST LIKELY cause of the problem, but not the only POSSIBLE cause. Then clear all the fault codes and drive the truck to see if this or the other codes return.

I have a 2000 focus with a p1120 code what can I do to start this repair.


Diagnostic Trouble Code (DTC) P1120 indicates that the Throttle Position Sensor (TPS) closed throttle position is below the range of 3.4 percent (0.17 volts). Possible causes for this DTC are:

· Damaged wiring harness or connectors

· Open or shorted Reference Voltage (VREF) circuit

· Faulty TPS

· Faulty Powertrain Control Module (PCM)

The methods/steps for diagnosing this code depend on how the code was stored and retrieved.

This code can be a Key On Engine Off (KOEO), Key On Engine Running (KOER), or a Continuous Memory code. To properly diagnose the cause of the problem a scanner must be obtained that has the ability to read each of these as well as the capability of reading live engine data from the PCM.

Direct voltage readings should be taken at the TPS connector and compared to the live data at the PCM. This will eliminate the possibility of a faulty PCM. The VREF and Signal Return circuits must be verified between the TPS and the PCM. Also the Sensor Ground circuit must be verified between the TPS connector and battery ground.

Yes, it is possible the temp. sender is faulty, but I would do a cross check of the actual coolant temperature vs gauge reading using a cooking thermometer in the top of the radiator.
Take care not to get scalded - check it at about 180 to 200 deg.
