How to replace the Throttle position Sensor on a Renix Jeep Cherokee XJ.<\/p>\n\n\n\n

My Dad’s Wagoneer has a 4.7 Stroker motor from Titan engines. It is lots of fun to drive. The wood grain panels make it kind of a sleeper.<\/p>\n\n\n\n

Lately it has had a couple of issues.\u00a0 First the torque converter would not lock up causing excessive RPMS on the highway. This did not help the already poor gas mileage.<\/p>\n\n\n\n\n\n\n\n

Second, it had a bad stumble transferring from closed throttle to part throttle. Sometime the engine would even stall if you did not give it enough gas or gave it gas too quickly.<\/p>\n\n\n\n

I hooked up my Renix Engine Monitor from Nick In Time designs and instantly saw tegh throttle position sensor value was out of whack.\u00a0 Nick’s software even gave a handy yellow warning light telling me something was wrong.<\/p>\n\n\n\n

After I confirmed it was not just a wiring issue, I ordered a new module from Amazon.\u00a0 Part number\u00a03i304650 .<\/a><\/p>\n\n\n\n

The sensor is mounted the throttle body with two Torx bolts.\u00a0 There are two electrical connection on the automatic version. I had to remove the air duct from the air box to access them.\u00a0 I also removed the vacuum line form the manifold to the valve cover connection.<\/p>\n\n\n\n

With the two screws out the c=sensor lifts off.\u00a0 Note that the sensor is driven by a tab on the throttle plate. Take care to properly line up the tab on the new sensor so that the throttle will turn it in operation.<\/p>\n\n\n\n

I found this was easiest done by installing the sensor at 2 o’clock and rotating it back to twelve to get the tabs to line up. Then I replaced the two screws.\u00a0 I had a bit of trouble reaching the lower one but I eventually got it.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Don’t tighten the screws down all the way just yet. Leave the\u00a0 loose enough to adjust the TPS base setting.\u00a0 This is 17 percent of the supply voltage.<\/p>\n\n\n\n

I used the REM scanner to set mine.\u00a0 Otherwise you will have to probe the wires with a volt meter and do some math.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The engine runs much better now with no hesitation.\u00a0 And the torque converter comes in just like it is supposed to.\u00a0 I will have to see if this repair actually helps the gas mileage.<\/p>\n\n\n\n
