94 E7 CH613 code 3-3


Recommended Posts

Hello,

My 94 CH613 with an E7 (non etech) engine just puked a code 3-3 on me :blush: . This is supposed to be a loss of signal from the injection pump speed sensor.

Can someone help with exactly where this sensor is on the pump? a photo of it would be helpful too.

Is this repair typically a wiring fault, or do these sensors really go bad . I can also appreciate it if I can find somewhere online (or local to Houston) to buy this part.

Thanks

OO

go to Mack to get the sensor, one on the pump one on the left side of the engine near the back on the bellhousing under the firewall.

Check connection at pump , bulkhead and FIC module . Pins 3 and 4 at injection pump main connection is your speed signal wires you can check resistance across both should b 800-1400 ohms if not problem is in pump pin 3 is your + line and 4 is-
