Question about 1994 Nissan Maxima

1 Answer

Emission control malfunction

I have a 1994 nissan maxima. While driving today, suddenly "Check" indication was lit up and upon chcking the manual, I understood that the error was related to some emission control problem. The car is vibrating when we come to a stop sign or so, but do not notice this vibration above 30 mph.

Can anyone please advise me if I could do anything about it? I went to a car mechanic he said it would cost $85 to just check what the problem and then would let me know.

Thank you

Error code 340 & 457

  • P0340 - Camshaft position sensor circuit malfunction.
  • P0457 - Evaporative emission control system leak detected (fuel filler cap loose/off)

    There is a bulletin #0398 posted on 05/12/2003 for P0457 - Malfunction indicator lamp (mil) illumination with diagnostic trouble codes p0442, p0455, p0456, p0457, p1442 or check fuel cap lamp illuminated with diagnostic trouble code p0457.

I'd suggest checking with your local dealer, as it may be a fix that is covered by the dealer.

Hi i have 1997 nissan maxima, emmision test got fail because of P0443 code, it runs well, could you help me tofind solution

P0443 - Evaporation Emission Control System Purge Control Valve Circuit

Hi. This code is referring to a malfunctioning Valve circuit, or defective purge solenoid.

The Evaporative Emissions System (EVAP) allows fumes from the gas tank to enter the engine to be burned, rather than vented into the atmosphere as an emission(emission control device). The purge valve solenoid is supplied voltage by the battery, and regulated by a switch. The ECM controls the valve by operating the ground circuit, opening the purge valve at specific times, thus, allowing these gasses to enter the engine. The ECM monitors the ground circuit as well, watching for faults. When the purge solenoid isn't activated, the ECM should see a high voltage on the ground circuit. When the solenoid is activated, the ECM should see the ground voltage registered as a low current, close to zero. If the ECM doesn't see these expected voltages, or senses an open circuit, this code is issued.


Symptoms could be just a malfunction indicator lamp (MIL) illumination. There may be no driving issues at all. But, it's also possible to have a lean condition or a rough running engine if the purge valve is stuck open. Usually, the symptoms are accompanied by other EVAP codes. Another symptom may be excessive pressure in the gas tank in the form of a over pressured sound when the cap is removed, indicating a purge valve that isn't working at all or stuck closed.


1. Bad Solenoid(mechanical failure, or shorted circuit)
2. Shorted control circuit, or bad harness connection
3. Water Damaged connection
4. Bad ECM/PCM


1. It is possible to use a diagnostics scan CPU to command the purge valve to operate, manually. Listen or feel for a clicking coming from the purge solenoid. It should click once, or on some models it may click repeatedly.

2. If it doesn't click, unplug the connector, and examine the solenoid and connector for damage(water). Check for battery voltage on the feed wire with the key on. If you have battery voltage, then ground the control side manually using a jumper wire and see if the valve clicks. If it does, then you know the solenoid is working properly but there is a problem with the control circuit. If it doesn't click when you manually ground it, replace the purge solenoid. If it dose click, this will confirm that the solenoid is functional, and the ECM/PCM will be the culprit(Damaged control circuit).

Does a 1994 Nissan Maxima need Super or Regular Unleaded Fuel?

all cars are designed to use a minimum octane rating of 89,(regular)
but if your car is computer controlled you may find it runs better on the higher grade(fill tank/check miles on odometer,do this a minimum of 5 times to check yourself as driving styles WILL effect mpg)

I have a 2002 Maxima 6 Speed Manual Trans. Under Heavy Acceleration the check engine light blinks several times and then goes off and stays off during normal driving. The light seems to come on as I hit...

U have an ignition related problem, have the system tested for the trouble code that is stored in memory any time the check engine light comes on to determine what is causing this issue. check engine lights have nothing to do with oil level or pressure, they indicate electronic control problems with the engine, trans or emission system.
