P2018 is a generic diagnostic trouble code (DTC) that indicates an issue with your Jeep Grand Cherokee’s intake manifold runner position sensor/valve (from here on out, we will be referring to this sensor by its common abbreviation of IMRC). P2018 Definition: IMRC – Switch Circuit Intermittent (Bank 1) IMRC The IMRC’s job is to help your … Read more
P0356 is a generic OBD II diagnostic code that indicates an issue with the ignition coil “F” (the sixth cylinder). Specifically with the primary or secondary wiring circuits. If your Jeep Grand Cherokee has thrown this code, it will usually be accompanied by P0306. Addressing P0356 should take care of P0306 on its own. P0356 is … Read more
P0355 is a generic OBD II diagnostic code that indicates an issue with the ignition coil “E”. Specifically with the primary or secondary wiring circuits. If your Jeep Grand Cherokee has thrown this code, it may be accompanied by P0305. P0355 is a relatively straightforward diagnosis and is typically caused by a bad coil pack or wiring harness issue, … Read more
P2198 is a generic diagnostic trouble code that indicates that your Jeep Grand Cherokee’s B2S1 O2 sensor signal is stuck rich. It does not necessarily mean that the vehicle itself is running rich (although it very well could). DTC P2198 is most likely caused by a bad oxygen sensor, although there are many potential secondary … Read more
P2138 is a generic powertrain code that can affect your Jeep Grand Cherokee’s “drive by wire” throttle system. It means that your Grand Cherokee’s “D” and “E” throttle position sensors do not agree with one another on how much far the throttle has been opened. They should have a similar voltage output. In this case, … Read more
P2196 is a generic diagnostic trouble code that indicates that your Jeep Grand Cherokee’s first oxygen sensor on bank one is stuck rich. It does not necessarily mean that the vehicle itself is running too rich. This code is the opposite of code P2195, which indicates the oxygen sensor is stuck lean. P2196 Definition: Oxygen … Read more
P2135 is a generic powertrain code that can affect any make or model of vehicle that has a “drive by wire” throttle system (almost every vehicle made today). P2135 TPS Switch “A/B” Voltage Correlation If your Jeep Grand Cherokee has P2135 it is considered “drive by wire”. Which means that it uses sensors and actuators to … Read more
P2197 is a general DTC code that indicates that the signal coming from your Jeep Grand Cherokee’s first O2 sensor on the bank two side of the engine is stuck giving off a lean signal. The voltage reading from a normal oxygen sensor should look something like a heartbeat, whereas with P2197 the voltage looks like … Read more
P2195 is a general OBD2 code that indicates that the signal coming from your Jeep Grand Cherokee’s 1’st O2 sensor on Bank 1 Sensor 1 is stuck lean. DTC P2195 is a general code, which means that it has the same meaning for any make, model, or year. It is most typically caused by a … Read more
P2272 in the Jeep Grand Cherokee is a general diagnostic trouble code. It means that the “bank 2” downstream oxygen sensor (behind the catalytic converter) is continuously sending voltage that indicates a lean air/fuel mixture. This does not necessarily mean that the vehicle is running lean (although it can, but usually doesn’t). P2272 is … Read more
