Fuel injection relay. It is located under the hood inside the fuse box. It is either red or green in color. It is one of the larger relays. This is classic symptom of these things going bad. The heat causes the relay to swell and not engage properly. They die out every couple of years. Usually the car will start again after it cools down.
asically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. The PCM detects that the actual MAF sensor frequency signal is not within a predetermined range of the calculated MAF value for more than 4.0 seconds.The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
Inspect for the following conditions: An incorrectly routed harness--Inspect the harness of the MAF sensor in order to verify that it is not routed too close to the following components: - The secondary ignition wires or coils - Any solenoids - Any relays - Any motors
A low minimum air rate through the sensor bore may cause this DTC to set at idle or during deceleration. Inspect for any vacuum leaks downstream of the MAF sensor.
A wide open throttle (WOT) acceleration from a stop should cause the MAF sensor g/s display on the scan tool to increase rapidly. This increase should be from 6-12 g/s at idle to 230 g/s or more at the time of the 1-2 shift. If the increase is not observed, inspect for a restriction in the induction system or the exhaust system.
The barometric pressure (BARO) that is used in order to calculate the predicted MAF value is initially based on the MAP sensor at key ON.
When the engine is running the MAP sensor value is continually updated near WOT. A skewed MAP sensor will cause the calculated MAF value to be inaccurate. The value shown for the MAP sensor display varies with the altitude. With the ignition ON and the engine OFF, 103 kPa is the approximate value near sea level. This value will decrease by approximately 3 kPa for every 305 meters (1,000 feet) of altitude.
A high resistance on the ground circuit of the MAP sensor can cause this DTC to set.
Any loss of vacuum to the MAP sensor can cause this DTC to set.
If you suspect the condition may be related to aftermarket accessories, refer to Checking Aftermarket Accessories in Wiring Systems.
I would lean toward the MAF sensor they were known for going bad, which would cause all these codes. It wouldn't hurt to take the IAC off and spray it out with carb cleaner and some WD40, just to cover your bases. Both these units were made by Bosch and the MAF failed alot more often then the IAC.
You can get the code from the dealer with the VIN# and you have to pull the radio out to get the radio's serial number. If you've tried too many wrong codes the screen will show error message. If so - disconect the battery for about 60 minutes to clear error message then reconnect and enter correct code
Try changing the fuel relay first. under the fuses, big relay. shop around for prices, it is expensive. if poss, go to a junk yard and find a used one and see if it helps. that way, if it does, you buy a new one and keep it in reserve for the next time. if it doesn't work , you aren't out alot of money, then we can go from there.
