What causes a Nissan Pulsar to miss a smog test?
3:Smog test failure usually means bad sensor. 4:Engine may idle roughly,hesitate,or stumble.A bad 02 sensor causes an engines air/fuel mixture to become too lean.Normally,a lean fuel/air mixture (too much air,not enough fuel)will cause a engine to miss,or misfire,especially when an engine is idling. 1:CEL may flash.
What causes a Nissan Pulsar to lose power?
3:Engine power loss and/or surging. 1:A faulty iac will cause stalling problems at idle. 2:Most of the time if you hold the gas pedal down it will run fine. These symptoms can also come from an EGR valve that is stuck open. 3: If you have a fast idle,check for an intake leak.
Why does my N16 Pulsar not start properly?
When the idle control valve dies in a Nissan N16 it can also screw the ECU (which was the case for me). The mechanics replaced the Idle control valve but there were problems with the electronics and engine wouldn’t start properly. They tested the ECU and the diagnostic tool was unable to connect with the ECU to obtain data from it.
What causes a Nissan Pulsar to blow head gasket?
If it takes a while to fire then likely poor fuel pressure probably from a failing fuel pump. If the engine struggles to turn its more likely to be water in one of the cylinders and thus a blow head gasket. I’ve heard the MAF can do this, but not so sure.
Why does my Nissan Pulsar N16 not idle?
Nissan Pulsar N16 1.6 and 1.8 DOHC 2000–2003 The engine would not idle or would idle too high or too low and the engine control module would not regulate the idle air controller (IAC) stepper motor. The Nissan Pulsar N16 range of engines are fitted with an IAC stepper motor.
What kind of stepper motor does a Nissan Pulsar use?
his case study applies to the Nissan Pulsar N16 1.6 and 1.8 DOHC 2000–2003 The engine would not idle or would idle too high or too low and the engine control module would not regulate the idle air controller (IAC) stepper motor. The Nissan Pulsar N16 range of engines are fitted with an IAC stepper motor.
What happens when the throttle position sensor fails?
The throttle position sensor can fail in several ways, all of which result in poor fuel economy at best, and performance limitations that may create safety hazard for you and other motorists at worst. This sensor can fail gradually, or all at once. In most cases, the Check Engine Light is illuminated if a TPS failure is detected.
What is the idle relearn procedure for a Nissan?
Battery voltage must be more than 12.9 V engine running at idle Electric load switches OFF. That means no A/C, headlamp, rear window defogger If you have daytime running lights (DRL) do this procedure to shut them off: BEFORE starting the engine: Apply the parking brake, or set the lighting switch to the 1st position.
