Question about 1994 Nissan Pickup

1 Answer

Check engine light goes on for a few days, then goes off for a few days. When I think its gone for good I'll go for a longer drive over some mountain passes and the light returns. Any suggestions, someone at the nissan dealership says this happens often in this year truck and its probably a faulty sensor. thx, greg

SOURCE: Check Engine Light 1996 Nissan Maxima

There is a silver box underneath the center console, just to the right of the gas pedal.

Pull off the plastic cover (it has two plastic fasteners. It will go back on).

Peel back the plastic film covering the screw.

Put the key in and turn the ignition switch on, but do not strt the car (all the warning indicator lights should go on).

Turn the screw all the way clockwise for two or three seconds and turn turn it back. Repeat just to be sure.

Turn the key off. When you turn the key back on the Check Engine light should be off.

Replace the plastic film over the screw and replace the plastic panel.

SOURCE: 2003 Nissan Altima 2.5S, Check Engine Light Problem.

My service engine soon light came on saturday on my 2003 nissan altima 2.5s, took it to the dealer and he stated I need a Catalytic Converter for the light to go off. Last yr Jan I had the same thing happen and there was a recall on the ECM they reset it for free. Any suggestions? I am so tired of getting ripped off being a single woman. The repair price they gave me was $940, my mechanic says he can repair w/new converter total charge of $300

SOURCE: Overheating

Here are a couple of suggestions.

1. Check to see if the electric cooling fans are working properly. Let the car idle until the engine gets hot. Watch to see if the dual fans ever kick in. If the fans never turn on then the problem could be the fans themselves, the fan relay, a fuse, or a temperature sensor.

2. Your thermostat may be stuck closed.

3. When the service engine light is on you can take the car to most auto parts stores and they will pull the codes for you for free. This could help to identify where the problem is.

Running the AC will make the car overheat faster because it loads the engine down. If you driving somewhere and you think you might be overheating and you can't stop to let the car cool down you can roll down the windows and turn on the heater. The heater works by pulling heat out of the engine and moving it to the passenger compartment. It may be uncomfortable but it can temporarily prevent your engine from overheating. This technique is especially useful if you're driving through a desert like in the southwest.

SOURCE: Crank position sensor for 2003 Nissan Altima

the crank shaft sensor is very easy to fix. the one i've dealt with was on an 03 micra so i'll be refering to that. Its on the front of the engine and usually has a green plug attached to it. pull of the plug and remove the 10mm bolt holding it in. pull the sensor out, (its not threaded) and give it a wipe. then put it back in, refix the bolt and reattach the plug, your done. if its still not working then the sensor might need replacing, nissan dealer only and about £90. robbery. i was told that the fly wheel on the 03 micra was slightly to big and caused dust to cover the sensor. good luck

Why did my check engine light go off on its own? (p1870 code)

The fault is gone. What ever caused the problem is no longer there.
When the computer no longer detect fault it shuts off light. Maybe transmission had a short time problem

Leaking coolant while parked and driving, leaking oil, tranny slipping and shutters and chirps when shifting, lagging acceleration, hard to drive up mountains

You need to have the cooling system pressure tested. This will tell you what and where the leaks are. The oil leaks are probably due to age of gaskets and seals. With age comes issues with vacuum lines too.

Diagnostic code p1624

Hi there:
DTC P1624 - MIL Request Signal active

This code is only the TCM (Transmission Control Module) telling the ECM (Engine Control Module) to turn on the check engine light.

If you don't have other codes there, could be a Communication Lost from the TCM; first I suggest to check all fuses and good harnesses conections correctly.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Engine light flashing and horsepower is low 2001 chrysler town and country

Hi there:

If the Check Engine Light comes on in the city but goes off on the freeway, then the fault is present during city driving conditions. Pay attention to whether or not the vehicle runs or drives any differently when the Check Engine Light illuminates. If vehicle performance does change, drive the car as little as possible and take it to be checked by a service professional as soon as possible. If there is no change in vehicle performance, you can drive home, but have it inspected as soon as possible. In this condition, you run a risk of the vehicle dying or not starting.

* The Check Engine Light comes on and stays on.
If the Check Engine Light illuminates constantly during driving with no noticeable driving or performance problems, there is a permanent fault in the emission control system. When this happens, the computer that controls the emission system usually has a backup program that runs while the fault is present. (These backup programs are often referred to as "limp home" mode programs.) You should get the vehicle serviced as soon as possible, but in most cases, the vehicle will continue to operate, though you run a risk of it dying or not starting.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Car will start but will only run for about 20 seconds

I had the same situation on my 2004 Touareg. The problem is the Fuel Pump. The Touareg has two. A primary and secondary. The primary on yours has gone out. The secondary is to assist with starts and secondary throttle driving situations like pulling a load or having a bit of fun in OD or sport mode. The part alone should run you about $350.00. However the tank has to be dropped from the vehicle to replace it. Should take no longer than 2 days max at a dealership. Mine was a one day job.

Hope this helps.
