SOURCE: what is P1111 AND P1647 on jaguar x-type

Hello! Code P1111 is pointing at a defective air temperature sensor.

Jaguar does not have a code P1647. However if the code was in the P164x area it is an effect not a cause; The air temp. sensor controls fuel flow by sensing a differential in temperature; This device is called a MAP. A small black component with two mounting bolt holes with an electrical connector. It cost around $80 if purchased at an auto parts store. Follow back from your air filter towards the intake (need to remove plastic engine cover) to locate the MAP.

If you need any additional information Please include it when you rate this solution.

SOURCE: my car has the code P0420 and p1111, which is what

p0420 refers to "catalyst efficiency low bank 1" and p1111 is air temp sensor circuit voltage high. replace your air temp sensor and it is probably in the mass air flow sensor so thats what going to be replaced. then have the codes cleared. cheers

SOURCE: What does diagnostic codes p0171, p0174 and p1111

I found two posts from the Internet regarding your p0171, p0174 and p1111 codes:

So your car's CEL (Check Engine Light) is on and you had the codes scanned at a local parts store. Your car has either a P0171, P0174 lean fault code or both stored in the computer, these codes are based on Oxygen Sensor (O-2) readings. A lean code or codes indicate that there's too much oxygen in the exhaust. Remember parts stores have employees that have good intentions but they may not have the experience necessary to interpret what the trouble codes really mean. These codes are based on oxygen measurements in the exhaust. A common mistake with lean codes is to replace the oxygen sensors. This could be a very expensive mistake that will not fix the problem. Especially if both codes are present, because the chance of both O-2 sensors failing at the same time is very unlikely.
Most likely the cause is a vacuum leak. A vacuum leak can be caused from a vacuum hose, intake gasket or maybe even a leak in the air intake hose from the MAF (Mass Air Flow Sensor). Listen for a hissing sound that may lead you to the source of the problem. Some technicians will use a propane bottle with a hose attachment to help pinpoint vacuum leaks. With today's computers it's not quite as easy to check for vacuum leaks this way because the ECU (Electronic Control Unit) will compensate quickly for the added fuel and a change in idle is harder to notice. Oxygen sensor readings can be monitored with a scan tool while checking for leaks with propane, by looking for increased readings when enriching the mixture. Another way technicians can check for vacuum leaks is with a smoke test. By introducing smoke into a vacuum hose on the engine, the leak will be revealed when the smoke escapes from the problem area.
Aftermarket air filters that use oil on the element can sometimes damage the MAF. Over oiling the air filter may allow some excess to get on the MAF sensor wire or element. This can alter the reading, fooling the ECU into seeing more or less air flow therefore changing the air/fuel mixture incorrectly. I once worked on a car that would not start that had a problem with a MAF. When looking at the wire in the MAF, there was a burned piece of trash that made it's way past the air filter. After cleaning the sensor the car ran perfectly. The ash that was on the MAF sensor wire was altering the reading by enriching the mixture so much that the car could not run. After talking with the customer, he said the air filter was just changed. This was obviously when some trash got into the air intake hose that settled on the hot wire of the MAF.
Fuel Pressure could also cause a lean condition. If the fuel filter is clogged or the fuel pump pressure is low, there could be higher level of oxygen in the exhaust also. Most of the time though, the ECU will compensate for the reduced fuel volume. So this is one of the least likely causes of a lean code.

I also got a code P1111 just after cleaning my MAS. The description from my reader was something like IAT performance problem. The problem never set the MIL light. I guess my only point is I did definately gat a P1111 as a IAT fail.

BTW, I believe it came from the temp sensor being wet -- the thermistor circuit most likely will read high if the sensor is wet. Mine was reading over 150 degrees F. Left the MAS in the refridgerator overnight and my problem went away (it is very dry inside a refridgerator). Sensor now reads correct.

SOURCE: what does the service code

Copied directly from a Jaguar forum:

P1111 is not a fault code. It is a special designator Jaguar uses meaning system ready, drive cycles completed after the last fault event. P1000, on the other hand, means system not ready, or drive cycles not completed after the last recorded fault event.

Some OBD II Basics - All P0xxx codes are generic and uniform across all manufacturers and mean the same on every car. All P1xxx codes are manufacturer specific codes. You cannot use a generic code chart to analyze P1xxx codes for a Jaguar.

Next time your car displays an engine fault light, try reading the codes then. If you have a CEL illuminated and the only code read is P1000 or P1111, then you probably have a fault that generic code readers cannot see. Could be a chassis code, for example.

One last thing - Neither P1000, nor P1111 can be erased.

Hope this helps you.

P1111 pathfinder


Four digit codes are brand specific. Code 1111 for Nissan is for a problem with the intake valve timing control solenoid valve for bank one. Bank one is the cylinder head with cylinder one.
You'll need a shop manual to get the testing procedures to check out the valve and the circuit to the computer.

P1111 Code


The P1111 unlike the P1000- the P1111 means the ECM has completed a drive cycle with no faults stored. The P1000 means the ECM has not yet completed the drive cycle. They are basicly drive cycle readiness codes doing a system check...this is a natural code..not to worry its checking the car all over between drive cycles for any malfunctions..
sorry i missed u online but the code is nothing to worry about...
