You can use some carb cleaner, spray it on a rag and wipe it clean
EGR or Mass air flow sensor
Trouble code P0401 means:Exhaust gas recirculation flow insufficient detected
Yes, you can still drive a 2002 Isuzu Rodeo with noisy lifters, but it's not advisable to do so for an extended period. Noisy lifters often indicate a problem with oil flow, which can lead to increased engine wear or damage if not addressed. It's best to have the issue checked by a mechanic to prevent potential long-term damage to the engine.
Unfortunately you do it with difficulty. Isuzu maliciously decided not to have a transmission dipstick on the transmission so the average guy cannot check it easily. Per the book, the transmission must be warmed to a precise temperature and then an overflow plug on the transmission is taken out. Fluid is added until it starts to flow out of the overflow plug and then you know it is full. it obviously must be done from under the vehicle. I would not have bought mine had I known this.
P0402, excessive EGR flow P1404, EGR range performance, valve closed Most of the time I find the EGR port in intake clogged. If you look in throttle body you will see a 3/8 tube plugged with soot. Clean and reset with scan tool.
no there is no kit. to check the fluid the truck must be level,warm and running. remove the top plug on the pan (which is on the pass. side)and fluid should flow out. its not easy.
how do you clean mass air flow sensor on a 1998 Nissan altima? To clean the mass air flow sensor , you need to get a can of CRC mass air flow cleaener frm auto zone, Kragen, Pepboys, Sensor is attached to the tube (next to airfilter). again you need to use mass air flow cleaner ( CRC ). I use this on my ford windstar and Nissan sentra 05 and 95. it runs better after cleaning the mass air flow sensor.
To tune up a 2000 Isuzu Rodeo, start by replacing the spark plugs and ignition wires to ensure optimal engine firing. Check and replace the air filter and fuel filter to improve air and fuel flow. Additionally, change the engine oil and oil filter to maintain lubrication. Finally, inspect the battery, belts, and hoses for wear and replace as necessary to ensure overall engine performance.
The P0402 code on a 2001 Isuzu Rodeo indicates that there is an excess flow of exhaust gas recirculation (EGR) detected by the engine control module (ECM). This can be caused by a malfunctioning EGR valve, a blocked EGR passage, or issues with the vacuum lines related to the EGR system. As a result, the vehicle may experience poor performance, increased emissions, or rough idling. It's advisable to inspect the EGR system components and related sensors to diagnose and resolve the issue.
It is located on the left side back for the engine looking from the front. Once u find it remove the two bolts and pull upward. Remove the gasget and use Carb cleaner to remove all the carbon deposits inside the EGR valve. This worked for me and i saved 110 dollars by not replaceing it. Works just like new.
In a 1995 Isuzu Rodeo pickup, the blinkers, gas gauge, and temperature gauge may stop working due to a blown fuse, faulty wiring, or a malfunctioning instrument cluster. A common issue is a blown fuse in the fuse box that controls these components. Additionally, a failed ground connection or a problem with the vehicle's main wiring harness can disrupt the electrical flow. It's advisable to check the fuses first, followed by inspecting wiring and connections.
Code P0171 indicates a lean fuel condition in your 2004 Isuzu Rodeo. To fix this, start by checking for vacuum leaks in hoses and the intake manifold, as these can allow excess air to enter the engine. Next, inspect the MAF (Mass Air Flow) sensor for cleanliness and proper function, and consider replacing the fuel filter or checking the fuel pressure to ensure adequate fuel supply. If these steps do not resolve the issue, further diagnostics may be needed to check the fuel injectors and the oxygen sensors.
