Where is the EGR valve located on a Honda Civic?
Where is the EGR valve located on a Honda Civic?
You will need a new EGR valve from your local parts store and a 12 mm socket wrench. After you open the hood of your car, locate the EGR valve. It is on the left, passenger’s side of the engine (see picture below). The valve is secured by two 12 mm nuts, situated on either side of the solenoid.
Can I drive with bad EGR?
Can I drive with a bad EGR valve? Technically, you can drive your vehicle with a bad EGR valve, but your vehicle will run rough, shake at idle, and a check engine light will be illuminated. You might also hear popping sounds while driving down the road.
What happens when EGR is blocked?
If the EGR system is clogged up, or the valve is stuck closed, the combustion temperature increases. This may cause pinging (detonation), as well as surging on light acceleration. In a diesel engine, a bad EGR valve is one of the causes of a black smoke. The Check Engine light might also come on in either case.
What does the p1491 code on a Honda mean?
P1491 – Exhaust Gas Recirculation Valve Insufficient Lift (Acura, Honda, Isuzu) Trouble Code Fault Location P1491 Exhaust Gas Recirculation Valve Insuffic
What does p1491 mean on a Saab?
Evaporative Emission Pressure Sensor / Fuel Tank Level Sensor In Fuel Tank – Range / Performance (Saab). What Does Code P1491 Mean? The Exhaust Gas Recirculation (EGR) system is used by the Powertrain Control Module (PCM) to recirculate exhaust gases back into the intake manifold of the engine in order to take up space where air and fuel would be.
What causes the p1498 code on the EGR sensor to stay active?
The most likely problem is the EGR valve / solenoid. If the P1491 code stays active and the P1498 does not set, we will need to test the sensor’s / solenoid’s associated circuits. At this point it may be wise to seek assistance from a trained automotive diagnostician.
What does error code p0401 mean on O2 sensor?
P0401 Insufficient EGR Flow – EGR valve movement detected but not enough change in O2 sensor voltage/ MAP sensor voltage. P1498 EGR Valve Position Sensor Circuit High – voltage on the sensor circuits are high/open circuit. EVAP Canister Purge Regulator Valve 2 Open Circuit – this typically indicates a canister purge valve circuit fault (Audi/VW).
