Where is the EGR valve on a Jeep Cherokee?
This is NOT the EGR valve! Where applicable (RENIX systems) the EGR valve is located on intake manifold. The white object to the valve’s right, held in place w/ a single screw in it’s center ‘nub’ with the two orange wires going into it is the ceramic fuel pump ballast resistor.
Where is the MAP sensor on a Jeep Cherokee?
Here’s a video of a YJ owner testing his MAP sensor. TPS and Idle Stepper Motor. Located on throttle body facing toward radiator. Located on the right side of the front of the throttle body. To test, disconnect the connector at the TPS. Check the voltage at TPS connector pins B (Ground) and A (5.0 volt supply) with the ignition on.
How does The Renix sensor on a Jeep Cherokee work?
Energizes the EGR valve solenoid to prevent flow of vacuum to the EGR valve. Update: Basically – this sensor functions by providing a resistance-to-ground circuit that the computer (ECU) uses to determine how much fuel the engine requires. (The hotter the coolant – the lower the resistance.)
Do you need a scan tool for a Jeep Cherokee?
You don’t need a scan tool! So if a diagnostic trouble code P0108 (OBD II equipped) or a DTC 13, 14 (pre-1995 OBD I equipped) is lighting up the check engine light (CEL) on your Jeep SUV, this is the article for you. This article will show you how to do a very accurate MAP sensor test that’s explained in step-by-step detail.

When to test the MAP sensor on a jeep?
Among those things are: a bad fuel pump, low engine compression, and intake manifold vacuum leaks. It’s always a good idea to check fuel pump pressure (with a fuel pressure test gauge), engine compression, and for vacuum leaks if your Jeep has a very high mileage engine.
Energizes the EGR valve solenoid to prevent flow of vacuum to the EGR valve. Update: Basically – this sensor functions by providing a resistance-to-ground circuit that the computer (ECU) uses to determine how much fuel the engine requires. (The hotter the coolant – the lower the resistance.)
Where is the O2 sensor on a Jeep Cherokee?
– Holley part #543-105 is an idle air control motor for Holley’s pro-injection system and will swap for this part for around $28 at AutoZone vs. $125+ at the dealership! Located in the exhaust manifold. To test, using an ohmmeter, disconnect the O2 sensor connector.
